Needed key fobs replaced.
Needed key fobs replaced. They were ordered and came in within the next couple days. Scheduled the service appointment and all was completed within two days. Have received great service upon all my visits.
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Thanks Marcin Kenny & Jimmy
An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!

I brought my car in for an oil change and multi point
I brought my car in for an oil change and multi point inspection. the inspection dealed that I a front brake issue. Mike, the employee I dealt with describe the issue and what it would take to repair it and how long I would have to wait he offered free transportation home if I wanted. because of the distance that I would have to travel there and back to home, I opted to delight the two hours in the lounge. I had coffee and water and I was fine. Mike came in several times to talk about the repair. He also said he had a rebate coupon I could use and he pointed out. I had points in my Buick awards account that I could convert to dollars to pay for the repair. That was very good service save me money and the car is running fine
