Dave Sinclair Buick GMC review
The salesman I dealt with, Rob Fulmer is one of the best.
The salesman I dealt with, Rob Fulmer is one of the best. Strait forward, tells you how it is without any hidden surprises. He was honest, patient and very professional. He easily addressed all my concerns and questions and I would highly recommend asking for him to be your salesman. He was very quick in responding as I was inquiring about a car out of state and he made everything very easy and simple to understand. Out of the other dealerships I inquired about, it was like night and day. I ended up replacing my engine in my old vehicle, so I didn’t actually buy from here but everything was set up to go I just had to sign. He was honest about out the door pricing and the dealership he works for doesn’t try sneaking ridiculous hidden fees like some of these other places. This review is the least I could do since I pretty much wasted his time. Thanks Rob and sorry again!

Nicki was wonderful, I will recommend her to everyone I
Nicki was wonderful, I will recommend her to everyone I know that are in the market for buying a vehicle. Jarrod was also fantastic to work with. Both very personable and made the process very pleasant when it had been made dreadful from trying to deal with other salesmen at other dealerships. These 2 were excellent. I've never had a better car buying experience. I'd been to 4 other dealers who wouldn't budge on price for the same vehicle. I was able to drive my brand-new car off the lot for $6000 less than the competitors offered WITHOUT a single haggle!
