2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Eric was very helpful and transparent throughout the entire car deal, from numbers all the way to driving out to view the car and finalize my purchase! If I could, I’d give him a higher rating than 5 stars for being very helpful and great to work with throughout the entire process!
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Compared to other dealerships, we were able to test drive
Compared to other dealerships, we were able to test drive the vehicles in a short amount of time while being provided only the information we requested. Thank you to Deion and Mark for letting take a car home over night. It was the most beneficial experience we had while car shopping yesterday. We will be going back to them in the near future once we figure out our financing.
Great vehicle

Eddie
I bought a Lexus LX570 from Greg. I was nervous as I never bought a car without driving it or over the internet. They delivered the car to my home and offered me more than a fair trade on my Mercedes. I was more than happy with the LX and Greg was great. I would not hesitate to trust Greg's word. It was a great buying experience and they did not disappoint me. I highly recommend this dealer.

“GREAT EXPERIENCE”
Salesman was very personable and friendly when my wife and I visited the dealership. The finance person was very friendly and very helpful when we needed financing the auto purchased. They both were better than the average dealer staff and I will buy my next auto from this place. The experience there was very easy and pleasant and I will highly recommend this dealership to anyone considering the purchase of there next auto.
