Beautiful car as pictured.
Beautiful car as pictured. Needed a number of things addressed that you could not see in pictures. Manager was very persuasive about making sure all the things that needed attention would be addressed but I was concerned that there was more than I could see in a short drive and inspection. Would need some more time to make sure that the vehicle was as advertised. Just not comfortable completing purchase Still a beautiful vehicle, was very hard to not complete purchase.

Excellent experience at Dallas Lease Returns.
Excellent experience at Dallas Lease Returns. Chris Mikell was great to work with. The entire process was quick and with none of the stress or pressure that often accompanies car buying. I would definitely buy from this dealer again!

I had an excellent experience at Honda thanks to my service advisor, Robert. From the moment I arrived, he was friendly, professional, and incredibly knowledgeable. He took the time to explain what my car needed in a clear and honest way, without any pressure. Robert kept me updated throughout the entire maintenance process, and the service was completed quickly and efficiently. My car is running better than ever, and I truly appreciate the level of care he provided. If you?re looking for someone who genuinely puts the customer first, ask for Robert. He made the whole experience smooth and stress-free. Highly recommend!

I recently purchased an Audi A6 from Epic Motors.
I recently purchased an Audi A6 from Epic Motors. The only complaint that I have is that I cannot give them more than 5 stars…they deserve it. Their professionalism, communication, timeliness and transparency were outstanding. From start to finish the process and interactions were not merely transactional but they were personable. Cristian, Mo, and Jose were excellent. Without hesitation I would recommend Epic Motors to others, and I would unreservedly purchase from them again.

I was online and scheduled a test drive for the next morning. When I arrived, Xavier Perez met me and had the vehicle ready for me. After I decided to purchase the vehicle, Xavier helped me transfer some items from my current truck to the new truck. He facilitated with the service shop to have my NFab boards removed and put on my new truck and even put on my new tags and removed the license plate holder and hitch holder. Xavier was professional, seasoned and knew what to ask and how to make my purchasing process go smoothly. He is an excellent example of a veteran sales professional at Young Chevrolet
