Micah was upfront about every single thing.
Micah was upfront about every single thing. He was also very helpful with all questions we had. Best purchase experience I have ever had so far. Favi was best with customer service listened to everything we said. Regardless of if it was her department or not. She had all answers if she didn't have it she didn't shy from getting any manager out to answer our questions.
So much better than prior GMC Yukon
I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

Best service department in 50 years of driving
I've driven many makes of quality cars throughout my life and have had many experiences with a multitude of dealers and service centers. Prior to Prestige Audi my best experience was with a Volvo dealer/service center, but the folks at Prestige have exceeded even them. I purchased my Q7 five years ago from Prestige and have had it serviced there ever since - and I have been 100% pleased with those decisions. It's been an extremely reliable car and I've consistently received the best service I could ever hope for, let alone expect. Everyone on the Prestige staff has been very helpful and courteous, but a special shout out goes to Lucas who has been my Service Advisor for most of the past 5 years. I truly couldn't ask for more from any business or individual. 5 Stars and 2 Thumbs Up!
SIGN ON GATELIFT COVER.
QX 80 is very comfortable driving. Despite it's size, maintenance is great. Thieves often mistaken the rear gatelift cover to be something valuable hidden inside thereby forcing it open and causing damage. May be a sign may be necessary. The current look is nice but attractive to thieves who have no idea of what it is.
