I recently visited Credt Nissan of. Frisco I was accompanied by a salesman named Terrance Coleman. Great guy very honest and made shopping. They’re very easy so if anyone try to buy a car from this dealership, please ask for this guy great guy thank you and you will thank me later
Most convenient options on any vehicle I've owned.
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

My wife and I traveled 2 1/2hrs to the dealership in
My wife and I traveled 2 1/2hrs to the dealership in Frisco, TX. We were treated extremely well from start to finish by our salesman, Jerome Collins. He worked with us on an acceptable trade-in deal and saw us through on a successful purchase. Very nice dealership with an exceptional free coffee bar, vending area, and showroom. Much better overall in-store experience than most other dealerships we've been to. Sales area did not have that claustrophobic feel. Would recommend to anyone.
This is your Truck
When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

Ryan Fields was a huge help.
Ryan Fields was a huge help. Really saved me a lot of time dealing with other dealerships because he had exactly what I wanted and was able to get me out the door as fast as possible!
So far have loved my 2020 2500 HD 4x4 diesel
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

I can't say enough about the positive experience I had
I can't say enough about the positive experience I had with Sewell New Car sales - specifically Macy Lane. She literally went above and beyond to work things out for me! Difficult circumstances led to me deciding to purchase a new vehicle right now. Macy is an exceptional person! Thank you Macy!!!

We had a straightforward, no hassle, seamless car buying
We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!
