I had the best experience at exclusive Autohaus bought a BMW 4 series from Exclusive Autohaus. It’s been six months since I bought the car no problems at all. Financing was really easy. Got the best interest rate. I am definitely going back in future to purchase another car. I did recommend the dealership to my father and he also bought a car from here.

We had the pleasure to work with Jim Jacobson.
We had the pleasure to work with Jim Jacobson. He is by far was the best salesman we?ve worked with. He gave us the best deal and was very informative. Not only was he giving us a great deal but he made sure we walked out with what we wanted. We looked over multiple options to see what would be the best fit for us. He made the long process into a great experience. I know we?ll be going back to Bill Jacob?s VW just for Jim! ??

This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Purchase of a certified Buick Regal
I live far from this dealership but they had exactly what I was looking for. The whole experience was very favorable . Everyone I has contact with was very professional and courteous. The salesman I worked with Joe Kendall was excellent. The day after the purchase I noticed that a light strip was missing on one of the outside mirrors. The service dept fixed it. In my opinion they are a top notch GM dealership . Keep up the good work😀
