I had a great experience at Westbank Legacy!

I had a great experience at Westbank Legacy! My Service Provider was very courteous and friendly. I was told what my car needed to have service/replaced. I was NOT pressured to get any extra service performed. My car, Envoy 2006, runs great!! Please be sure to tell the mechanics what a great job they did to my Chester! Thank you!!

Crown Buick GMC review

Mr Kenneth Simms was the best Salesmen.

Mr Kenneth Simms was the best Salesmen. I didn't want all that normal Salesmen fluff. I wanted a car for my retired Mom who's car was recently totaled and I wanted it quick. I did my research, called with the exact car and my specs, and he LISTENED. He was patient, professional, and knowledgeable and above all accomodated our needs. Bottom line, he was selling a car and we were buying one. Mr Kenneth made the DEAL. Even delivered a car to my Mom in Gonzales, then met us at the dealership on his off day to deliver her actual vehicle. Thanks Mr Kenneth! God Bless.

I had a very satisfactory experience.

I had a very satisfactory experience. The required service was explained to me so that I understood exactly what needed to be done. The service personnel, also, explained and suggested what services needed to be done in the future. This information was very much appreciated.
