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.

I bought two cars from Mike Barrows.
I bought two cars from Mike Barrows. Mike's salesmanship goes unmatched. He did not pressure us at any point and was always willing to do his best on a price for us. The transaction was quick, easy and smooth. Just to top it all off Mike donates $50 dollars for every car he sells to united for the troops and having two grandparents that served this really blew me away. Thanks Big Mike!
GLC43AMG
I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

Made an offer and they will notify me if price comes down,so all is good!!
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.

Highly recommend Beverly Hills Motors
First time ever purchasing a used car and found BHM online. I live in MI and was somewhat apprehensive about buying without seeing in person but only in photos, but car was everything I thought it would be. Sales associate Nader lead me thru the whole process and answered any questions I had and was very helpful and friendly. I'm now driving around in my S5 Audi and loving it and would HIGHLY recommend this dealer, and if you find what you're looking for make sure and ask for Nader and tell them Jeff sent you.

this was the second time that I was in for what I consider major repairs. Initially, the service tech and I didn't hit it off very well. Then Tim the service manager stepped in and was great to deal with. The repairs were completed in good time and they did a fantastic job. I'm happy I chose this dealership.
