Diamond Chevrolet Buick GMC Cadillac

I am not much of the “review” type person, However, I feel this company is worth the time. From the days when I had nothing and no one, they have always treated me with respect and helped me any way they feel this company is worth the time. From the days when I had nothing and no one, they have always treated me with respect and helped me any way they could. I remember having terrible credit, a single cab truck and having another child on the way and no other vehicle. They did what they could to help me. I have purchased what seems my hundredth truck from them now. I have watched the salesman grow from salesman to managers to general managers. I have seen this dealership keep salesman instead of being a revolving door. To my belief, that is because it truly is a family dealership. From the late grandfather, to david, the son, and now Jonathan the general manager. When you enter that dealership they make sure you are part of the Diamond family. Not only are you a customer buying a vehicle, but years later the service team will also always back you up. If you want a GMC, Cadillac or Chevy- Diamond is the place to shop. More

Very deceitful practices of showing vehicles in stock on lot, even after texting to confirm, then you drive some distance to get here,and None of the 4 Sierra, 1500 SLT's as shown online and confirmed are lot, even after texting to confirm, then you drive some distance to get here,and None of the 4 Sierra, 1500 SLT's as shown online and confirmed are on the lot, but they will try to sell you the more expensive Denali model or a lifted chevy elevation, both with being sold as new, but with significant mileage in them... with no apology or even an ounce of remorse. This all happened after much online discussion with a seemingly intentional lack of good communication. Don't waste your time with this dealership... but.. this has been much more the same experience at so many GM dealerships in this area anyway. Very disappointed and not surprised that GM is losing business and cant keep dealerships open when they accept and endorse these type of deceptive practices. More

The Perfect Place to Have your Car/Truck damaged SEVERAL of these points made are blatant lies, as this is a misrepresentation of events as occurred, we will provide a fully detailed and accurate dep SEVERAL of these points made are blatant lies, as this is a misrepresentation of events as occurred, we will provide a fully detailed and accurate depiction of our experience. Our Silverado was towed to Tony's automotive in Grafton, MA. The issue was a sensor in the fuel pump, something only a dealer could repair. We had AAA tow the vehicle to Diamond Auto Group. We were on site at Tony's automotive with our technician when AAA's fleet service tow truck pulled our truck onto it's flatbed. The bumper was observed by shop workers, the tow truck driver as well as our selves as to not have damage on the front. Whereas 161,000 miles may be a fair amount of mileage, we do take care of our vehicles, and maintain very good bodywork and pride in our Chevy. When we arrived to pick up our Truck from Diamond Service, we saw bright BLUE paint MATCHING the blue on the car lifts inside the workshop. Understanding this towed vehicle would have needed a push could explain how the body damage occurred. We asked to speak the Service Manager (Christian) regarding the newly found damage. The response from Christian was verbally aggressive with my wife, whereas I intervened-and The Service manager changed his tone and promised to investigate surveillance footage, and that he'd get back to us. ONE WEEK later I followed up with Christian regarding the results of his 'investigation'. To my surprise, he admitted he had not attempting to look into the videos, and that we needed an estimate from a body shop (which we did -same day- (Ray's Autobody in Grafton, MA quoted at $513.15), he asked for any available footage, and the color of Tony's Automotive's' lifts (they are yellow). We called back after giving him several days to review his 'footage' again, and it was at that time that he offered us $150 (for the FIRST time- NOT THE DAY AFTER (they never got back to us to offer us anything), and Never asked us for the Autobody quote he'd asked us to get previously. In that conversation, my wife explained that the tow truck driver at AAA verified that the truck had no damage to the front bumper prior to or after the tow occurred. At this point, Christian's response was, and I quote; "I could say that the damage didn't happen here, I could even put it in writing. It doesn't matter. But I'm being a nice guy here and offering you $150 when I don't have too." My wife responded by stating that she may go through insurance, and his response was; "That's fine. It'll still cost you your deductible." At this point, my wife had stated that the $150 was not sufficient as all parties are aware that the vehicle was undamaged prior to arrival at Diamond Auto's Service Building/Lot. He reiterated that $150 offer out of "good faith", and then we explained we'd be following up with other means. We followed up leaving Joe Simons, General Manager two separate voicemails, to which he was unresponsive. the issue remained unresolved with Christian. The first response we received from Joe, was to our negative Facebook review, two full weeks after the phone interactions with Christian and a month after the initial incident took place. Joe asked my wife on Facebook to reach out to Christian to handle any service issues after being unresponsive to us when we reached out to him directly. This bring us to current. Damage is still there, dealership has done nothing to rectify their wrongdoings. More
