Xpel We invite all Porsche owners who share our interest in Porsches to join the Porsche Club of America. When you join PCA, those of you in the 37 county area around Houston will become members of the Lone Star Region. We encourage members to participate actively in the various Club events. Regardless of the kind of Porsche activity you choose and the model of Porsche you drive, LSR can be a place to meet and enjoy our activities with a great group of friends.
