Awesome experience from an amazing company
Well I unexpectedly discovered that I was in dire need of transportation and had no clue where to begin. Fortunately, I remembered that I had a Consumer’s Reports subscription and decided to give them a try. They not only gave me ideas about make and model they included reliability and recommended dealerships. The first one I called couldn’t see until the next day. The second one I called was Andy Mohr Speedway Chevrolet. Honestly, I wasn’t even sure what exactly I wanted but the efficient and kind staff helped me quickly narrow things down and picked out the perfect car for me. They also worked with me with financing options, insurance and even getting the license plates!! I am frankly amazed that I have a beautiful car with everything I need without any issues! They even helped me set up the OnStar system!! Definitely an awesome experience from an amazing company!! 😊❤️❤️❤️
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Excellent experience
I dealt with Paul Lundgaard at BMW South - he was fantastic! He went out of his way to get me the vehicle I was looking for. His experience with BMW was very apparent, and made our buying experience top notch. I would highly recommend him and Dreyer & Reinbold when making a BMW purchase
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Bull Estes Lebanon review
The only dealer I go to now. Scott is the best salesman I have ever bought from. He knows the products and explains everything so I can make my decision on what will fit my needs. Gary in service makes sure my vehicles are properly maintained without trying to over sell me on what i don't need. I was a mechanic a very long time ago and appreciate honest repairs.

Moses is the go to guy for 7.3 excursions. Hands down my favorite salesperson. Answered all my calls immediately, even after hours. I will buy another vehicle from him before anyone else. Great sense of humor also. I bought it from out of state with no problem. Moses made it very easy. Thank you Moses 😊

I just have to give a huge thank you to the team over at
I just have to give a huge thank you to the team over at Indy Luxury Motor Sports! After visiting several dealerships, I finally found my dream WRX with the help of Jeremy and the crew. Their professionalism and willingness to work with my credit situation made the entire process smooth and stress-free. It was a refreshing change from the typical car-buying experience. If you're in the market for a quality vehicle and exceptional service, I highly recommend giving Indy Luxury Motor Sports a visit. They definitely know how to take care of their customers!
