Affiliate Chapter of Buick GS Club of America

Greetings Buick Enthusiast!

Thank you for your interest in the Southern California Chapter of the GS Club of America (GSCA). Let us explain what out our organization is all about.

Our chapter, the Southern California Gran Sports (So Cal GS), was founded by Oliver Colteryahn in March, 1992. Since then, our membership has steadily grown to approximately seventy member-families. Like the national club, the primary purpose of So Cal GS is to share information about our Buicks and to participate in automotive events. We encourage the recognition, acquisition, restoration, maintenance and all around enjoyment of performance cars built by the Buick Motor Division of General Motors. Regardless of whether your car is a daily driver, show car, cruiser, street rod or race car: if it's Buick powered you're welcome to join.

Our club members are constantly helping each other with maintenance, restoration and performance tips.

You'll thoroughly enjoy the camaraderie of others in our club who regard Buick automobiles as highly as you do!

Our best regards,
Southern California Gran Sports
