Got transportation to home while repairs were being made
Got transportation to home while repairs were being made with a nice guy. The repair was not as scary as I thought it would be.
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.

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!

Entire family has a car
Brought my daughter to look at a new car. Put her in touch with Brook Winter. She walked away with a new GMC Arcadia. She is so very happy with her new SUV. She also was so pleased at the service she received from the time we entered the door until we left 3 hours later. We now have 2 Cadillacs and now she has her SUV. Will always recommend to someone looking to buy.

Great Experience
After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.
