Dean Team Volvo Cars of Saint Louis review
Lemme tell you about them
Lemme tell you about this dealership. This was THE easiest and fastest deal I have ever experienced. Bob Chitwood is the truth. I met with him on a Saturday for a test drive. By Tuesday I drove away with my new car. He handled everything little detail BEFORE I arrived to sign all of the paperwork. Everyone was super nice, knowledgeable and relaxed. Would I buy another car from them, yes. Is Bob Chitwood a thoroughly great salesman? Yes!!! He was soooooo good at his job, my bestie-who was with me for the test drive -also drove off the lot with a new car. Love. Them.

Meier Chevrolet GMC review
Great customer service
Very helpful staff. Absolutely no pressure to buy from Corey during the early phases of my shopping . Visited multiple dealers trying to find the right vehicle. When made decision on vehicle Corey and Steff did all the work. Online questions answered almost immediately. Even stayed late to accommodate my schedule. No hassle buying process. Made the 50 mile trip well worth it. Will definitely look here when in the market again.

Laura Buick GMC review
Overall good drove over three hours to arrive, pain that
Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.
