Professional and superb customer service. Was dealing with a check engine light. They go out the way to make sure customer is taken care off.

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

The experience was great. Worked the numbers over the phone and nothing changed when I arrived onsite. They value creating long term customers.

I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.
