Would never do business here , EVER AGAIN! BUYERS BEWARE!!

By JordanG on 6/15/2018 at 4:28 PM. Helped by Todd.

SAVE YOURSELF THE HEADACHE AND GO TO IMPERIAL IN MENDON OR ANY COLONIAL DEALERSHIP! Would never buy a vehicle from them again, sold me a “used” suburban that was used and traded in by one of there own, purchased it from them beginning of August 2017, battery died within a few days, took 2 days and many calls from me for someone to give them “clearance “ to put a new battery in it. They never changed out the brake pads and rotors like they said they would (figures salesman puts “resurface” in purchase and sales and they didn’t even resurface them.) I had to call many many times about my brakes squeaking, they proceed to tell me they did them April 2017, so it sat not driven for 4 months so brakes/pads were all rusted and squeaky. Rear tailgate pistons both broke within a few weeks of owning , 2 of the 4 tires had leaks within a few days outside the 30day guarantee, mind you I had put in well over 40 calls to there service department, my suburban I had just bought for my wife ! From her own cousin who works at diamond,! was in service for almost 2 weeks of that first month I owned it, with them always saying “I don’t have clearance” to do that and leaving me helpless. Not to mention end of September ( almost two months since bought ) my suburban starts acting up and misfiring and brought to mechanic and has a hot cyclinder 7, which keeps blowing spark plugs and misfiring , I’ve put 2 sets of plugs in under a year, and have to get oil changes sooner as it burns oil , I would never buy a vehicle from them ever again , used or not they had a vehicle on there lot and sold it to me and my wife (her own cousin sold it) and has BEEN NOTHING BUT PROBLEMS, the vehicle should of never been on there lot and they know it and that’s the reason they treated me like dirt after I purchased it, they lost business from me and my family that’s for sure Mind you when I finally plugged into snap ons advanced controller found over 20 codes that were cleared before I purchased the vehicle Be aware of them!! They will rip you off in service, and beware buying used anything and new from them!! Shop around there are dealers local who are THOUSANDS CHEAPER more than willing to be upfront and honest with you . This was copied from my review from google, they are liars and snakes and did not do any of that except ONE key fob, and REAR ROTORS ONLY NOT EVEN PADS!!! they are thief’s and snakes and should not be in business at all. ****MY RESPONSE TO DIAMONDS LYING RESPONSE** I have records and conversations saved to prove none of that was done AT ALL!!! (Tires, rotor and pads ), they did two back rotors because I threaten to get a lawyer involved. ADDITION - I DID NOT RECIEVE 4 NEW TIRES AT ALL!! I DID NOT RECEIEVE THE FRONT AND REAR BRAKE PAD AND ROTORS, YOU ONLY REPLACED THE BACK ROTORS BECAUSE THERE WAS RUST SPOTS AND RIVETS IN THE ROTORS, YOU DIDNT EVEN CHANGE OUT THE PADS LIKE YOU WERE SUPPOSE TO!!! YOU GUYS ARE SUCH A JOKE AND LIARS ITS PATHETIC AND SICKENING , NONE THE LESS THAT AN EMPLOYEE WOULD SELL HIS COUSIN A VEHICLE LIKE THIS !!! You guys ought to be ashamed selling cars with known problems to people , never mind family members. MIND YOU I HAVE ALL THE TEXTS, EMAILS, and CONVERSATIONS SAVED BETWEEN ME AND THE SALESMAN WHO SOLD ME THIS PIECE OF JUNK, I HAVE ALL RECEIPTS YOU GUYS ARE ABSOLUTE LIARS , I RECIEVED NO NEW TIRES, NO NEW PADS ALL AROUND , I HAD TO FIGHT AND FIGHT AND CALL AND CALL FOR YOU TO PUT ON REAR ROTORS!!! YOU GAVE ME ONE REMOTE WHICH TOOK 2 WEEKS TO COME IN!! COURTESY VEHCILE? IT WAS OUR ONLY VEHCILE AT THE TIME AND WE HAD GOOD FAITH YOU WERE SELLING US SOMETHING RELIABLE AND SAFE , and a service 9/21/17???!!!! LOL , THAT WAS THE LAST TIME I BROUGHT IT IN AND YOU GUYS TOLD ME “THERES NOTHING WE CAN DO ABOUT FRONT PADS AND ROTORS AND THE TIRES “ , you guys are con artists , PLAIN AND SIMPLE!!!!!

I would not recommend this dealer.

FAILURE TO HONOR

By LouEthier on 4/1/2018 at 2:12 PM. Helped by George/James.

This dealership does not honor monetary or verbal agreements. After a week or so of traveling 1 hour each way to view and negotiate the price of a truck, I put down a deposit and filled out the required finance paperwork and was scheduled an appointment on Monday, after the holiday weekend. They called me on Saturday morning and scheduled Monday's appointment and it was just hours later that they called me and told me that the truck was sold to SOMEONE ELSE!! . I do not recommend ANYONE to do ANY business with this dealership. They are NOT honest nor do they keep their word!!!!

I would not recommend this dealer.

Classic Bait and switch

By DPSElias on 9/1/2017 at 1:06 PM. Helped by Gary and Mike.

This has been one of the worst experiences I have ever had dealing with car dealers and I have had very negative experiences with independent used car dealers. I will start with that I live an hour away in NH without traffic, so I contacted the dealer about a used truck they had on the lot and wanted to work out a deal before I drive down, I talked with Gary early in the day said he couldn't work anything out without seeing my trade as they don't discount their trucks but will over compensate on the trade being it's the end of the month, so I sent him several pictures and talked to him about the condition of the truck he did not ask many questions but told him it had some rust and had over 100k miles so he can give me a range I told him I have been quoted for $23k-$24k for my trade and if that was where they would be the deal wouldn't work so he said he'll present the images to their GM. Gary contacted me within the hour saying they own the auctions and they have sold vehicles with over 100k miles on the lot before and gave me a range of $28k-$31k I questioned this and talked to him on the phone to confirm and said if you can get close to $28k then the deal could work without discounting your truck. I got home gathered my things and rushed to get to the dealership since they said last day of the month is my best chance to get this deal so they can move the unit, driving through rush hour on 495 and 290 which took us an hour and a half to get to the dealer to show I am serious about working a deal, showed up at 6:45 pm, I was met by Gary and Mike, they told me to take the truck for a test drive while they work out the numbers, took a 15-20 min drive up and down 390, we then waited another 45 min for them to get me the numbers, we waited outside as the dealership was extremely noisy and it was a very nice night outside, when they finally came back their best foot forward was no discount on their truck and the trade went down to $23k, they told me my truck was tired and it has rust (I did not hide any of this) then they said well we range what this truck is work through 2 systems to see what the going rate is (why wasn't this done in the afternoon before they gave me a range) and that they just received this truck in from a trade and they can't over trade for my truck. Moral of the story is that it doesn't matter, this dealership will lie to you to get you in the door and they pull a bait and switch and won't work with you to make a deal and their motto on the add "We won't be undersold or out-traded!" is a complete lie, same truck a year older and only 6k more miles is $8k cheaper, so they are being out sold and out traded at a dealer 20 min from my house. I would not waste your time like they wasted mine.

I would not recommend this dealer.

Issue with a repair Bill I thought unfair

By mike122569 on 6/17/2016 at 9:29 PM. Helped by Ron Caswell and Mitch Hadaad.

I brought my car in for brake service after having brought it in a couple times previously but finding I didn't need brake pads at that tie. Unfortunately this time it was too late and I was told I needed rotors as well. Now for those that don't know, rotors can go bad for many reasons but it was hard for me to not blame the dealership for not listening to me the last 2 times. When I spoke with Ron Caswell about my disappointment I was hoping that he would understand and explain to me why this happened and why I now had to pay a lot of money. Ron was beyond helpful! He listened to me and acknowledged my concern and explained to me some reasons why this could have happened without making me feel as if he was just brushing me off. In the end he did something beyond my belief and far above what was needed. He did it for no other reason than to show me that this dealership is there to be a partner and not an adversary. I have been sold on Cadillac for 10 years now and probably will buy a new one soon. I will not go anywhere else because of this great manager and the treatment that left me feeling like a valued client. Thank you again Ron. I will be telling everyone who will listen what a great bunch of people you have working in this dealership. Regards, MIke Egan

Dishonest and disappointed at each stage of buying process

By Moses123 on 2/2/2016 at 1:20 PM. Helped by Joe Spears. Bob Carter.

I found an attractive vehicle online. Went to Diamond to check it out. Vehicle had a vibration issue. The tires looked new so I was concerned . The salesman told me they were aware of the vibration and not to worry, we will fix it. We sat down to talk about financing. The salesman brings out a sheet of paper. $18,000 financed., $439 per month 60 months. Asked what rate is that. He tells me 6%. I told him I don't think so. No where on the sheet did the rate show. I asked again what's the rate that, not right. "It the same rate everyone gets, between 6-9 percent. " he tells me. Now I'm irritated because I know I'm being lied to. I told him to double check the rate. He steps out of the office in his fancy suit (way to tight) and comes back shortly after. I just spoke to the finance guy, your right it's between 9-12%. . I pulled out my auto loan calculator (Apple I phone app) and showed him, his loan was closer to 15%. I called him a lier and walked out. To be continued........

I would not recommend this dealer.

Your Basic Bait and Switch

By roopestang on 4/21/2015 at 3:35 AM. Helped by Maurice.

Saw a great deal online ($2,500 below market value) on the exact make and model I wanted. Even though it's a little bit of a drive I thought I'd head over and see it. My research told me the car I wanted had been on the lot more than 175 days. I figure I'm in luck. They want to move it and they're willing to eat a loss to get it off the lot. When I get there the car has a big SOLD sticker in the window. Darn it. I figure the odds of that are low but all cars eventually sell, and it was attractively priced. Maybe I was a day or two late. I tell the sales guy I'd had my eye on that specific make and model (without telling him I'd researched this specific car online). Funny thing - suddenly it's not quite as sold. It's just got a deposit on it. And they haven't heard from that guy in a few days. And would I like to test drive it? Sure. So I test drive it while they try and get Mr. Deposit on the horn to see what he's going to do. Red Flag 1: If you have earnest money down on a vehicle, do you want the dealer letting people test drive it? After the test drive, red flags #2 and #3 pop up. Red Flag #2: The dealership has not reached Mr. Deposit. They make it clear that they really don't care about his deposit anymore. They will sell the car out from under that guy here and now. They want to talk price. This isn't an honest business practice. Red Flag #3: I know the asking price they have advertised online. But I ask the sales guy what his asking price is. He quotes a number $4,000 higher. This is when I let him know that I've scoped this particular car and that I know exactly what their advertised price is. I've just caught him in a $4,000 lie. He pretends it's an amazing deal that is so new he didn't even know about it. Also a lie. With my misgivings growing, I sit down to talk price with them. They won't budge on the sticker price. OK fine. I even tell them I'll finance through them so they make a little extra on the deal, but I need to walk away unscathed on my trade. They lowball the trade offer by thousands. That's when I walk away. I go eat lunch, hit a couple other dealers that don't have any cars that excite me. I decide to make one last shot at this car because it has a very particular combination of features that's hard to find. I offer my highest and best. I'll pay their sticker if they'll come up to a fair market value on my trade. That's when... Red Flag #4: The "buyer" rematerializes. Suddenly, the car I could have bought an hour ago is not for sale to me at any price. But why don't I come in and look at their hundreds of other cars on the lot? Only two scenarios are possible: 1. They actually had a buyer and a deposit for this vehicle, and they were unethically shopping it to me. That's shady at best. or... 2. There was never a deposit or a buyer, just a classic bait and switch. They throw an unbelievable price out there for the online comparison shoppers, something to get them on the lot to see if the deal is really that good. And it is, if you're willing to pay their sticker price and then let them kill you on the trade. If you don't roll over, they pull that option away by pretending they sold it just now and try to steer you into something else that is more profitable. Either way, it's shady dealer nonsense. I ended up buying at another dealership the same day with considerably less baloney involved.

I would not recommend this dealer.

By JWA2013 on 10/14/2013 at 10:50 PM. Helped by Shannon Smith, Dana, Joe & Frank Bromley.

This is an edit from from my last post. In fact, it is such a dramatic reversal of events, that I deleted the post and chose to write one more appropriate to the situation. I will spare you the details, but suffice to say, the dealership stepped up and stepped up big time. They changed a negative feeling & experience into a dramatically positive one. The bottom line? I would deal with this dealership again. I will refer my friends to Frank and I would, without hesitation, recommend The Diamond Auto Group to anyone searching for a GM vehicle. Especially a Cadillac. Well done Diamond team, well done. -James Alexander

By fday on 9/23/2013 at 9:17 PM. Helped by Fran Daviau, Derek DiFederico.

My name is Frank Day and I just purchased a 2012 Chevrolet 3500 HD truck at Diamond Auto Group. My sales person was Fran Daviau. He could not do enough for me to ensure that my experienced with Diamond Auto Group was as pleasing and easy as possible. No pressure sale, allowed myself and wife to inspect the truck and test drive it as much as I wanted to ensure that the truck was what I was looking for. The day I picked the truck up I purchased a set of fender well inserts and he made arrangements to have them installed for me. As it turned out the truck was exactly what I was looking for and I enjoy it very much. Fran is one of the best car salesman that I have done business with. Derek DiFederico was the financial person that handled the paperwork, I should mention that I live in New York and that made Derek's job much more challenging. He had to deal with NYSDMV, NY state tax, my insurance company and a few other issues. He went far out of his way to ensure that all of the paperwork was complete and error free. He explained everything to me and my wife and made sure that we had no questions and fully understood what was going on. If I did not live in New York I surely would be a customer of yours for service but as it turned out you are two and one half hours from my house, just a little to far for service. You can be sure if I know of anyone looking to buy a new or used vehicle I will end them your way. Once again thank you, Frank Day

By aydtxn on 4/16/2012 at 10:12 PM. Helped by Michael Deppe, Lisa (Owner's Wife).

STAY AWAY FROM THIS "STEALERSHIP" !!!! I came there to purchase a brand new 2012 Cadillac SRX AWD….. A salesman named Michael Deppe let me test drove in one…. We negotiated and agreed on the price upon an invoice of a 2012 SRX AWD. When I was asked to pick the one with the interior that I like, it turned out the one that I picked was a FWD. The salesman did not say anything nor even adjusted the price to the FWD which is $2500 less than the AWD. When I spoked to the salesman about this matter, he promised me this promised me that but none was delivered. The worse part is, he will pick up his cell phone in a heartbeat before the contract is signed, when the problem occurred, you can never reach him through his cell phone. When I asked to speak to the General Manager about the problem, he transferred me to the owner's wife named Lisa. After the salesman told her what I was complaining about, she said she was gonna go pull the deal from the computer and NEVER COME BACK. She had someone else deal with me. I asked them to give me some accessories instead to make up for the difference and all the owner can give me is a stupid pitiful "discounted price on parts and labor". He said that was not his fault when clearly his salesman give me the FWD with the AWD's price. They kept on trying to convince me to trade my car for the AWD so they can take advantage of me again. THEY ARE JUST THIEVES WHO ROB PEOPLE'S HARD EARNED MONEY LEGALLY! PLEASE SAVE YOURSELF ALL THE TROUBLES AND GO TO ANOTHER DEALERSHIP!
