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!
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.

Engine light came on, rough shifting, Adam in Service
Engine light came on, rough shifting, Adam in Service dept fit my truck in for diagnostics within a week. Tech found bad coil, replaced and repaired, also suggested new wires and battery was needing to be replace really low crank, all work completed and again on the road after 310,000 miles. I have had only good experiences with the service department staff and techs. Sometimes it cost some money but its a machine and if you take care or it, it will last.
