Excellent dealer to buy a vehicle from, and none of the games like some others like to play.
Josh was our salesman, and he was very knowledgeable on the vehicle we purchased, as well as a pleasure to deal with. No high pressure, and straight forward explanations of details.

So I have been dreading looking for a new vehicle. I reached out to my friends on Facebook and asked for recommendations. Over half who commented said to go to Mark Allen Buick GMC. Then like 4 people said to ask for Lyndsey Blakely. So last week I called and spoke to him. And today I was finally able to get there to look at cars and discuss things. I must say it truly was a great experience. I never felt pushed to get a vehicle I didn't want. Lyndsey is definitely not the stereotype pushy car salesman. He was fantastic to work with. He is down to earth and really worked to get me in something I needed and wanted. I am the proud owner of a 2021 GMC Terrain! Thank you so much Lyndsey!
