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.
