My appointment made my car drop off go well; I had a mini
My appointment made my car drop off go well; I had a mini as a loaner which was a delight as I got to see new features that my 2023 does not have. The lounge is a wonderful asset with a nice size television, books, snacks, water, etc. I like the text received with video and audio explanations of what was found during the car inspection.
Love at first drive
I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

It was great working with Brent!
It was great working with Brent! He was professional and polite and quickly resolved my problem! Brent also pays attention to to details! Service like this is important to me!
Awesome!!!
I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

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!
Sedan vs SUV
Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.

Had a really good experience at Southtowne Mitsubishi! CJ was great! Loving the fuel economy on my new PHEV! I would recommend anyone to go try them out!
A fun and enjoyable ride!
Yes, it’s crazy powerful but you can definitely tame it to be a fully enjoyable ride for everyday use. I look forward to many years with my new X3M!

Amazing Experience
We were in the market to purchase 2 vehicles. One we knew exactly what we were wanting and had actually found Velocity by looking for that vehicle. We searched around for a few weeks but kept going back to the vehicle that Velocity had listed due to the lower price, lower mileage and overall value. We finally pulled the trigger yesterday and went in to test drive the vehicle. Instantly fell in love and ended up finding another vehicle on their Draper lot for our second purchase. Between Ty, Cory (American Fork location) and Efrain (Draper location), they made the process extremely painless, got us the cars we wanted at a great deal and worked with us on our trades. We walked out with the payments we wanted, the vehicles we wanted and literally no hassle or pressure from anyone. Nothing makes me want to run the other way then being hounded by a salesman instantly and feeling pressured. We felt none of that here with Velocity. We couldn't have been more pleased with the service and quality we received. Thanks again for the great experience. We will be sending friends and family your way.

I've bought a lot of cars over the years and Alex and the management at Streetsboro VW made this the easiest purchase I can remember (except for the 500 mile drive to get there!). Throughout the process they were reasonable and easy to work with. I was completely satisfied with the buying experience and would highly recommend the dealership to anyone looking to purchase a car.

I would recommend this dealership and service to anyone who is interested in purchasing a new or used vehicle. Not only did they have the exact vehicle I wanted but they went above and beyond in assisting me with answering my questions and making my experience with a vehicle purchase the best one I have ever experienced. My salesman, Robert Hammond, was extremely knowledgeable and was great to work with and next time I need a vehicle I will be going directly to Robert.
