Ross Downing GMC of Gonzales review
Easy to set up appointment for service.
Easy to set up appointment for service. The facility is extremely clean. Car drop off was seamless and car was ready when the service staff said it would be. I was late picking up the car, so they made arrangements for me to pick it up from the showroom which was very kind considering it was the weekend. The staff took care of billing to my flleet company.

Our salesman, Landon Crane, is new and even didn’t have
Our salesman, Landon Crane, is new and even didn’t have his business cards yet but he’s gonna go far. He was extremely polite, willing to answer questions and had no problem getting up to ask about an answer he wasn’t certain of. I appreciated he wasn’t pushy, condescending, or fake. He may be young and just getting started but you won’t go wrong by requesting him for your salesman. The young man knows how to give an appropriate handshake on top of all his other positive qualities. From start to finish it was a relaxed buying experience. Give him a call!
