Suntrup has been the best dealer i have worked with. I spent a very short time there making the purchase. That was great. Sleigh and Gerald were awesome to work with.

Knowing you spent minimal time here and found the process effortless is rewarding for our team. Ashleigh and Gerald were pleased to guide you through the purchase of your new C1500.

Your praise of Ashleigh’s patient guidance and clear explanations during your purchase of a used Chevrolet Blazer EV highlights the attentive service our team strives to deliver. Knowing you left both satisfied and well informed means a great deal to us. Thank you for recommending our team!

My wife bought a vehicle here on a Friday. I went to the dealership with her the next day to drop off a few documents but had no intention of buying another vehicle. After a quick meeting with James and a test drive he found the vehicle that was perfect for my needs and made the numbers works. Very happy with my experience and new ride!

Our salesperson, Ashleigh, was amazing! She’s relatively new, but was very effective in finding answers to our questions if she didn’t already know. I feel like the sales manager should have been able to do better on the price, but we are very happy with our vehicle and the fine treatment we received from Ashleigh. The car was cleaned and gassed up in a reasonable amount of time and the financing person, Bob, did a nice job of explaining all of the warranty options. Overall, a good experience!

My experience was not a good one during this visit. The center kept my car for eleven days. They would not offer a loaner car even though I was paying $3,500. I was told for insurance purposes. This makes no sense to me. I would call about the progress of my vehicle but would have to leave a message with Kaitlin (No matter what time of day I called), only to not have her to return my calls. She finally reached out after 4 days via text message. She did not communicate the status of my vehicle very well. I ultimately missed work, because I could no longer afford my rental after one week. I was told that my vehicle would be available on the following Tuesday but did not hear anything until days later. I also, asked Kaitlin that since they had my vehicle so long if they would add an emission and inspection. She informed me that they would add that service, and informed me of the additional cost. However, they did not do the safety and emission, and I was to bring it back in, after them having my car for 11 days. When I finally picked up my vehicle, the person checking me out was rude and told me that I had to pay an additional fee for using my credit card for the $3,500. I will never return to Suntrup.

Thank you for this feedback. We're very sorry to see that you didn't have the best experience at our dealership. While we're disappointed to learn that we didn't meet your expectations, we'd love to try to turn things around and make sure the same thing doesn't continue to happen.
