Highly recommend anyone buying a car to buy with Thorton Automotive Dover! Made everything smooth, easy and stress-free while I was in a bit of a rush to buy and I live out of state. I am so thankful for all of their help, and I drove off of the lot in a beautiful vehicle that I would not have thought was in my budget. No questions asked, I will recommend them to everyone in search of a new ride.

BEST CAR BUYING EXPERIENCE EVER.....These people really go to the extreme to help you get you into a vehicle that is what YOU want. To say my credit was less than perfect is quite the understatement I was on the low side of poor for my credit score and I was laughed out of other dealerships I had inquired about a vehicle at Thornton automotive and I had been texting with Desiree their super customer service ambassador. She told me to stop by that they could do more for me than anybody else and they did. Kelly Raber and Sales manager Chuck really went to bat for me and they were able to not only get me financed but I was able to drive away with an extremely loaded SUV. They actually treated me like I was the most important customer they ever had. Five stars it's not near enough for this company as far as I'm concerned they have a customer for life.

I’m really glad I came to Thornton to get my car. A friend recommended it to me and I really think they were the best option. All of the staff members are incredibly friendly and professional. I worked with Chris Shade and he was fantastic. He did everything he could to work with my situation and make sure I left the dealership with a car that I loved and could afford. I’d like to think any of my future car purchases would be done through them as well. 10/10 would recommend.
