Just purchased my first MB from MB of Ff.
Just purchased my first MB from MB of Ff. Mitchell. I’ve bought MB’s from other MB dealers in the past. This was the best experience, due in part to the outstanding service from Sales Rep. Trent Nipper. Dealership is high touch in every respect.
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.

Kendall was an amazing saleswoman.
Kendall was an amazing saleswoman. I love my car and the way I was treated
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!

My daughter Kiyamma bought a Santa fe sport a few months
My daughter Kiyamma bought a Santa fe sport a few months ago and it has been great. I would like to thank you for her great experience.
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.

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!

I recently purchased a 2024 Lincoln Navigator from Heiser
I recently purchased a 2024 Lincoln Navigator from Heiser Group. I was pleasantly surprised at the amazing customer service they provided and the follow up to make sure I was happy and satisfied with my new vehicle. This is something I haven't experienced before so I felt like I was quite a special customer. They let me try out several vehicles to insure I had exactly what I wanted!! It's nice to see this customer service is still available as this experience was a far cry from my last vehicle purchase at a different dealership (no names mentioned). I left the dealership confident I made the right decision and I am confident I will be supported in any of my needs going forward. I will never purchase from anyone other than Heiser going forward. I recommend that everyone purchase their vehicle from Heiser!!

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.

Tiffany made selling my car super easy and stress-free. She was upfront, honest, and really helpful through the whole process. I ended up getting more for my vehicle than any other dealership had offered me, and it all happened faster than I expected. No pressure, no runaround—just a smooth, transparent experience. If you’re looking to sell your car, definitely reach out to Tiffany. She’s the real deal!
