i sent an email to my dealer to see if they used this company and they gave me the name of the company they use. however, i found the website for the company they use and i sent him an email back to let him know that i didnt want to use his company because the products looked cheap and they didnt have the particular item that i wanted. im still waiting on an answer. i remember going to another dealership and they showed me the product and i am sure it came from invision industries. does anyone know if invision industries is the dealer installed company that buick uses?
