The St. Louis Region of The Porsche Club of America is part of PCA Zone 10. The majority of our members reside in the St. Louis Metropolitan area including Central Missouri and Southern Illinois. The St. Louis Region of the Porsche Club of America was the 14th Region to be Chartered by the Porsche Club of America. Of the original 14 charters, 4 of those regions have since disbanded. This makes the STLPCA the 10th oldest region out of 140 in the country. The STLPCA is also the largest region in Zone 10.
