I just bought my car here 5 months ago and it has been a great buy these past few months. Kellen was super helpful and kind. I also traded in my old car and they gave me a good deal.

Velocity Auto Sales review
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.

Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck
