Jim Monroe and I got along fantastically, He was super

nice to work with and I've been in sales for 66 years for three other companies and now own my own business. He thinks like I do: "treat your customers the way you'd like to be treated". "THANK YOU" again, Jim Brad M.

Jim Monroe was one of the best salesman I've worked with.

He was very polite, knowledgeable, and honest. No pressure sales and had me in a new truck in no time. Thanks Jim!

Jared Brown did an excellent job!

He was very helpful, knowledgeable and allowed us to take our time in making a decision on our new GMC Sierra EV purchase. The rest of the team at Dave Sinclair did a great job as well. Thank you Jared and team!

Great dealership, worked most of my deal over text and

phone. They listened to what I wanted and I was in and out picking up my new vehicle. I enjoyed the buying experience to where I almost wish I'd have spent more time with them.

Fast and friendly service.

The sales team (Nikki) will get you what you want. The finical department adds the finishing touch with a low-interest rate tons of options that fit that fit what I was looking for.

I had one of the best experiences for a car purchase.

The atmosphere in the showroom was pleasant and friendly. Paul Christopher made my process a breeze. The price was upfront; my concerns were heard and addressed. I got preapproved through my credit union but got a better interest rate from the finance department. The process was quick. There was a bit of a wait between all departments seen in the process, but nothing overly excessive.

I had a fantastic experience purchasing my new vehicle at

Dave Sinclair Buick GMC. From start to finish, everyone I interacted with was professional, respectful, and truly focused on providing excellent customer service. My salesman, Josh Morgan, was outstanding—pleasant, knowledgeable, and never pushy. He took the time to answer all my questions, knew the vehicle inside and out, and made sure I felt comfortable with my decision without any pressure. Nick, the manager, was also very kind and respectful, making the process smooth and enjoyable. Randy, the finance manager, was great to work with, handling everything efficiently and professionally. Alex was another helpful and pleasant team member who made the experience even better. Dan, another manager, also assisted and was just as respectful and professional as the rest of the team. Overall, from top to bottom, everyone at Dave Sinclair Buick GMC made this a great car-buying experience. I would absolutely buy from them again and highly recommend this dealership to anyone looking for a new vehicle. A well-deserved 5-star rating!

I came in only looking to test drive an Envista after

having a bad experience with another dealer nearby. Josh came out and was really friendly introduced himself, asked a few questions and offered a test drive. I want to make it clear that I had no intention on purchasing a car that day, I was actually in the market for a Jeep Wrangler but curiosity and frustration led me to Buick. Before the test drive was even finished Josh had unintentionally changed my mind and convinced me that I needed that Envista! Josh made me feel so comfortable, he let me know that he was about earning my business the right way by creating a deal that worked both for me and the dealership. Because Josh was so personably I decided that I wanted to purchase my car from Dave Sinclair Buick! I would also like to add that they were closing and no one rushed me out or tried to rush my decision, a few of the other sales man came even came and introduced themselves just to be kind. I also need make mention of Randy in finance, he’s such a nice guy, he’s not your typical finance guy, just there to get signatures, he explained everything and made sure I understood everything I was signing, he even gave me some good fatherly advice lol! Lastly Alex! Alex assisted me the day of delivery as Josh was off, this man has the patience of Job, I had to do a set up call with on-star and he made sure to stay with me until my Envista was all set up and ready to go, he even helped unload a few things from my trade while I finished my call with Onstar! Whenever I’m ready to make another purchase I will definitely be returning to Dave Sinclair Buick!

I drove over 8 hours to pick up truck.

Did as much of the paperwork as possible prior to arrival. Financing was preapproved. In and out relatively quick. Main issues was with quality control of the truck. The 2024 2500 GMC Sierra AT4 was filthy. The saleswomen Nicki was kind enough to run it through details again while we finished signing paperwork. I made a mistake and did not look at the truck a second time after second detail, when I arrived home I noticed a large scratch on the roof of the cab by the cargo lights. I spoke with Nicki who spoke with her boss and was told, tough luck, nothing can be done due to the truck leaving the lot without documentation of scratch. I was told the truck was fully inspected 2 or more times but I am certain this did not happen after the second detail. I believe this is when the scratch occurred. I feel the scratch should be corrected as it was a new truck with damages. I am completely certain it did not happen after my leaving the lot.

Don’t ever do business with this dealer!

They have no morals and don’t give a xxxx about the customer. TWICE in one week they sold a truck to someone else for which I had already started the process of buying over the phone since I was out of town. The second one I actually had a signed sales order for. Don’t believe anything else they may say to the contrary.

I would not recommend it due to the interaction of a

potential purchase. I had a deposit on another car (F150 Platinum) that I had reconsidered but the Sierra AT4 caught my eye (60K). The issue was that I was refinancing my house and could not run credit, so I offered a 5K deposit and they refused to hold, so I offered 20K (bank check in hand) still they would not hold for 5 days. 5 days later the salesman called who was great saying they still had the vehicle, but unfortunately the sales manager that day was "Dave Sinclair Jr" who said that was not how we operate and he has kids too. I killed me to respond to the sales guy with a pic of my new truck saying your boss killed the deal not you

Great Customer Service

Although I ended up not purchasing a vehicle from here I had one of THE BEST customer service experiences with Oscar. He drove me to the overflow lot, allowed me to drive & when I became indecisive & felt discouraged he kept on trying to find something to fit my wants. However, I was on a tight deadline & was unable to find a car that I liked & within my budget. I just wanted to thank him for working so hard for me, suffering through my stubbornness and all. He remained nice & professional. I hope this review counts for something even though I did not purchase anything.
