I recently purchased a 2026 Chevy Colorado from Mossy Chevrolet, and the entire experience was excellent from start to finish. Adam, my salesperson, was outstanding—very knowledgeable, patient, and always willing to answer my questions. The entire staff was friendly, professional, and made the process smooth and stress-free. I truly appreciate the level of customer service I received and would definitely do business with Mossy Chevrolet again. Highly recommended!

Carfax Jun 7, 2026

Mossy took care of everything, all I had to do was drop of vehicle and they did the rest.

Carfax Jun 7, 2026

Invoice said twice, vehicle was washed. I asked the mechanic when he brought the truck out of the shop, if he was going to wash it it, he said the car wash was down, compressor broke, ??? so the truck was not washed. Small thing but was mystified by that.

Jordan worked hard to get me a great deal on my car! Trade in value was reasonable. Me Joey helped finalize things and the finance dept was great with securing the lowest possible rate.

Rhonda is the best

Google May 26, 2026

Ask for Joey! He is the best sales person I’ve ever dealt with when buying a vehicle. From that time my husband and I walked in the dealership l, almost 2 months ago, until now he’s been great! We had some hiccups but they were all beyond his control. He went above and beyond for us even when he didn’t have to!
