Excellent experience July 4th!
Excellent experience July 4th! I went in around 6 PM and was out by 7:30 PM with a new truck. From the sales associate, Tai Trinh, to his sales manager and the financial manager, I had 100% satisfaction throughout the entire process. Thank you for the exceptional service.
Nicest, best performing truck I've ever owned

JR in service did a superior job for me once again. There are two dealerships closer to my home, but I find the extra driving time is well worth it with the value & service provided by Richardson Chrysler Jeep Dodge Ram. Thanks again JR in service!

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

The dealership was fantastic overall.
The dealership was fantastic overall. I worked with Charles Van Horn. He was great, very accommodating and laid back. Lane in finance was very difficult to work with, however. A simple task ended up taking several weeks, his communication and service was extremely poor. That is the only reason the review isn't 5 stars. I will probably go back for my next vehicle because of how great everything else was though.

Working with Ethan on my 1st ever online purchase
Working with Ethan on my 1st ever online purchase - was the 1st experience everyone wants! He was efficient with communications, but never pushy. He was flexible and open to any questions, while walking me through the process! Friendly, knowledgeable, and great to work with. The financing process with David's help was a breeze! The process was time efficient and pretty flawless. He was on point with communication and very knowledgeable. Still loving my new car 2 months later- it exactly what I wanted and drives like a dream!!!
