2020 GMC 2500 AT4

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Jerry Hunt Supercenter review

I had made the mistake of scheduling a service

I had made the mistake of scheduling a service appointment at the Salisbury dealership but my appointment was at the Lexington dealership what a blessing it was they waited on me which they didn’t have to so glad they did they saw something the needed attention and took care of it I could go on and on but I want just saying they treated me better than I expected I will drive further to go there even if the other ones are closer

2020 GMC Sierra 2500 AT4 review

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.

Corwin Honda Colorado Springs review

I recently purchased a 2025 Honda HR-V Sport from Corwin

I recently purchased a 2025 Honda HR-V Sport from Corwin Honda, and I want to give special recognition to Morgan Holt. From start to finish, Morgan made the process smooth, straightforward, and stress-free. Even when I had concerns or felt uncertain, Morgan went above and beyond to make sure I got into the right vehicle and felt confident about my purchase. He stayed responsive, professional, and genuinely cared about getting me taken care of—even following up with me regarding my loan documents. What stood out most was Morgan’s commitment to customer service. He didn’t just sell me a car; he made sure the entire experience was positive and that I left feeling supported. It’s rare to find someone this dedicated in sales, and I absolutely commend him for it. If you’re looking to buy a vehicle, I highly recommend asking for Morgan Holt—you won’t regret it.

2020 GMC Sierra 2500 AT4 review

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.

Bridgeland Auto Brokers review

Kevin was amazing!

Kevin was amazing! He wasn’t pushy and made looking and buying a car fun again. #1 salesmen in my books. Bridgeland and Candy Cars had a variety of Wranglers that were quality cars. Kevin also had the Jeeps I wanted to test drive waiting right up front for me! Once I bought my Wrangler, it was serviced, inspected and cleaned waiting for me upfront. I’d do business with them again.
