Maverick Motors is great!
Maverick Motors is great! They went out of their way to ensure I was getting a great vehicle for a great price. They had the best price compared to dealerships across the nation. I purchased the vehicle sight unseen and had it delivered. Made me a little bit nervous. However, everything they claimed about the quality of the vehicle was true. They keep their word. They sell good vehicles. Matt was my sales agent and he is the man! I highly recommend Maverick Motors.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

The Best Used Car Buying Experience I’ve Ever Had I went
The Best Used Car Buying Experience I’ve Ever Had I went in on a Saturday to purchase a car for my son, and from the moment I walked in, the experience was top-notch. I was fortunate to be helped by Haley, and I truly cannot say enough good things about her. She provided the best customer service I’ve ever received at a car lot—professional, knowledgeable, and genuinely caring. She is a true asset to the company and honestly deserves to be paid well. She's the reason I stopped shopping around and knew this was the right dealership for us. Although I came in during the afternoon and ended up staying late, not once did I feel rushed. Every staff member I interacted with—Haley, Steve, and the team in the business office—was kind, patient, and thorough. They followed through on everything they promised, which gave me full confidence in the purchase. I’m super happy with the entire experience and would highly recommend this dealership to anyone looking for a quality used car and outstanding customer service
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Bought 2 Cars Here, Now Going Back
Bought a car here. After several years I traded it in and bought another. Values were fair on my trade-ins. Vehicles on the website are really the ones they have on the lot. No pressure, no negotiating, huge selection. Paperwork process like normal. I did have to refinance after I left there because the interest rates were steep and I got better deal from credit union. Overall recommend. Had a car accident, will return to Carmax.

This was an awesome experience getting repairs completed.
This was an awesome experience getting repairs completed. Very professional service rep. Everything was explained before work was done. I knew the price and approximate time to get work done before it started. Very satisfying experience with the repairs and overall service experience.

My experience at this dealership was great!
My experience at this dealership was great! Garret was my salesperson and he was very experienced and did a great job helping with my car purchase. He gave me the keys and I knew it was the one. I test drove the car and it drove perfectly. The tires looked pretty new and the inside had no damage. The cars on their lot are very clean and maintained. Sam was who I worked with on the financing and he was very thorough in explaining all the options that I had. All the people there that I met were very nice and friendly. I would definitely recommend this car dealership.

Best car buying experience I've ever had.
Best car buying experience I've ever had. Jason was so helpful with the finance and sales part. We were in and out in less than an hour. I was worried about hidden fees like the other dealerships i shopped at, but Dallas cars have none. They earned a customer for life

We thought our journey with Mini was coming to an end.
We thought our journey with Mini was coming to an end. Drove our Countryman for 7-8years and it?s been so good to us. Then we received an offer from Mini that we had to check out! Now we?re officially extending our mini experience with a new 25? Countryman thanks to the wonderful people at Mini of Dallas! Kevin was our sales guy and he walked through absolutely everything with us! Patient, detailed, passionate and professional. Kevin made us feel comfortable and made this experience as smooth as possible. We weren?t able to do too much research on the car beforehand but we definitely learned a lot about our new car by the end of it. Ron, who helped with the finance side, also made this experience very easy for us. He understood where we were coming from and exactly what we wanted out of this whole deal. Financing and warranties are always that tricky and not-so-fun part of the car buying experience. Our talk with Ron was totally different from any of my previous experiences. We managed to get a great deal on our new car and am very happy for it! Overall, probably the best car buying experience I?ve ever had. And the 2025 Countryman is just amazing! Great car, great staff! Thank you Mini of Dallas!
