Thank you Nick & A.W.E., in Plano Texas.
I had a 2018 all black challenger, and decided the color just wasn't for me. Nick Barbera gave me a smoking great deal on my trade in for a beautiful 2020 Challenger in indigo blue. It has a cinnamon red leather interior, and I am very happy with this car. Hats off to all the good people at Auto Web Expo in Plano Texas!!! I would recommend them to anyone looking to upgrade from the car they have, to the car of their dreams.
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.

Very Helpful
Went to this Carmax off of an advertised vehicle. Vehcile was as advertised with no hidden charges or add-ons. We wanted to look at others and the salesperson walked us through all available vehicles. We ended up wanting to see one at another Carmax They set up arrangeents and we went to the other Carmax and purchased that vehicle. Both dealerships were very helpful and courteous. Price was better than other dealerships and there was no haggling. Actually a very easy buying process. I have not found a better price at ay other dealership in the area.

We drove 5 hrs to this dealership to come look at a Chevy Traverse. Jenny Jo received us with a friendly attitude. At first, we didn’t make a deal due to the trade on value on our vehicle. Jenny suggested we try to sell our vehicle at a place she recommended. And that’s what we did. We came back and got the deal finalized. They were really patient and answered all our questions.

I look forward to buying here again
We were pressed for time & needed a good, reliable truck. Our young son was leaving for Illinois in a few days. We almost literally ran into Kevin on his way out of the gate-Lol! He stayed a little late & showed us a great F150 trade-in he had just gotten & made a great deal out of it for us. He had it detailed, inspected & mechanically checked out for Josh to get on his way. I believe Kevin was sincerely invested in our son’s well-being for this road trip. Of course, Josh made it without a hitch! Thanks again, Kevin & God’s blessings on you, your family & your great business! 👍🏻

Vanessa and one of the managers ( can't recall his name)
Vanessa and one of the managers ( can't recall his name) were extremely helpful. There was some confusion about the scheduled maintenance and what was covered and what wasn't. I explained to Vanessa and the manager what had been communicated to me by Graff Chevy & Brandon at Classic...they reviewed everything and completed the service based on what was communicated to me and sorted out the other communication internally. Additionally the service was completed in half the time I expected. Previously, I had a challenging experience with the body shop so Classic was not my first choice for this work, but I decided to give you a other try and it worked out far better. I'm pleased with this service and thanks again to Vanessa and the service manager she engaged to assist.

The buying process was surprisingly quick and easy. The dealership was actually very willing to negotiate the price with me and once we agreed upon a sales price, there was no hours-long waiting like I have experienced at other dealers. Our salesman, Javier, was very attentive, gave me his cellphone # and responded quickly to me with a couple of questions and requests that I had after the purchase. Overall, very pleasant exerperience and I will be returning to this dealership in the future.
