A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I don’t write many reviews but I felt one employee
I don’t write many reviews but I felt one employee deserved to be recognized. Celenne M, the Title Clerk. After leasing a car from another Gettel location more than two months ago, she inherited my problems. The title, tags and registration had to be transferred from another state. Additionally, I had numerous changes in paperwork to do and temporary tags to change out. It has been a frustrating situation. And took a lot of work. She constantly kept in touch with me and took care of everything without me having to contact her. This is made it could’ve been a really difficult and unhappy experience a good one. Thank you
Very comfortable to drive and relax in!
This truck was exactly what I was looking for! Great ride, and it will haul every thing that I need it to.! Low mileage without new car up front expense!

I reached out via cars .
I reached out via cars .com about a specific car that I seen on their website. I got a response the same day. It was by a gentleman whos name is Joe at Winter Park auto exchange. He took some video of the car i was curious about. I went a few days later to actually check it out, with my wife. Car was exactly as advertised, clean low miles. So the purchase was lightning fast. I test drove it and did all the necessary paperwork in probably 30 minutes. They have a lot of inventory. If your in the market, please check them out. Great people!!!

I recently purchased a vehicle from Genuine Motor Company
I recently purchased a vehicle from Genuine Motor Company after finding it through an online marketplace—and I’m so glad I did. Even though I was a several hundred miles away, the entire experience was smooth, honest, and well worth the trip. From the very first interaction, Devin was outstanding. He was responsive, informative, incredibly easy and even fun to work with. He answered all my questions promptly, sent detailed information and photos, and made sure I felt confident about the vehicle before I even arrived. His transparency and professionalism really stood out and was much appreciated. My second interaction was just as outstanding. Kyle was there to quickly address any questions and was instrumental in making sure all the paperwork was processed making the transaction quick and transparent. Behind the scenes, Sam helped every step of the way making it as smooth as possible. When I made the trip to pick up the car, everything was exactly as described—no surprises, no pressure, just a clean, well-maintained vehicle ready to go. The entire team was friendly, supportive, and clearly committed to customer satisfaction. It’s rare to find a dealership that makes long-distance buying feel this effortless and trustworthy. I’d make the drive all over again without hesitation and would highly recommend Genuine Motors to family and friends. Genuine Motor Company is exactly what the name says—genuine, through and through. They truly went above and beyond! Do yourself a favor and contact Devin if you are in the market for purchasing a car and see how stress free it really can be.
