Easy process with no haggle pricing.
Easy process with no haggle pricing. The dealership had the price broken down, and did not throw in a bunch of add-ons. It made the experience much more pleasant.
This truck has a jerk when changing gears sometimes.

I recently purchased a vehicle from Top Line Auto, and the experience was outstanding from start to finish. The team was incredibly knowledgeable, attentive, and genuinely committed to making sure I found the perfect car. They went above and beyond in providing detailed information about the vehicle, including mileage, Carfax history, and available warranties, which made me feel confident in my purchase. The process was smooth and stress-free, with no pressure or rush to make a decision. I also appreciated their willingness to work with my schedule and accommodate my needs. The level of customer service at Top Line Auto is truly exceptional, and I would highly recommend them to anyone looking for a quality vehicle and a hassle-free buying experience.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.

We had an excellent experience with Wells Auto Group.
We had an excellent experience with Wells Auto Group. Our salesperson, Artie, was helpful, straight forward and honest. The negotiation on price was upfront and friendly, and we believe we got a good, fair price on our new vehicle and trade-in value on our trade vehicle. Kudos also to Dale in the Finance Department, who was extremely patient and helpful. I drove 9.5 hours to execute the trade and pick-up, and it was easy and seamless. Great work Artie, Dale and everyone at Wells Auto Group who made this a really good experience.

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!
