We bought a work truck last year in October and are now buying a family vehicle. The truck we bought is beautiful and runs great. I will be buying from them in the... More

I recently purchased a truck from North Texas Truck Stop....from NY!
Perhaps the easiest and smoothest transaction I've had when buying a vehicle. From across the country nonetheless! Upstate NY is not kind to vehicles...finding a specific year, make and model that is rust free is nearly impossible up here. They make the entire process easy from start to finish. No pressure from staff to purchase, and super responsive to any and all questions. Once the sale was complete, they took care of the s... More

Great experience. Had the paperwork ready when we got there, no sitting for hours like every other dealership. First price was a fair price so no need to argue back and forth. Met the whole staff, just really great folks. We have bought many vehicles and this was the first time I actually enjoyed the process. Next time we need another truck, these are the only people I want to work with. I wish them many more years of success.

This place is top notch, from a great website design and setup to professional fast customer support and an unbelievably CLEAN inventory. You will not find another place that compares to North Texas Truck Stop.
Ryan was my sales guys for my new vehicle, he made the process easy, quick, it was a very comfortable space; NOT the stereotypical sleezy car salesman vibe.
