Every year, Z3 (and now Z4) owners make the trek to Spartanburg, SC, where the cars were made. This year, TC Kline Racing brought their Carbon Coupe, based on the BMW Z4 M Coupe. Z3 owner, photographer, and attendee Doug Richardson took some nice photos of the "TRAK STR."

The annual west coast meet of Z3/M Coupes took place at Half Moon Bay, CA this past weekend, with about 50 Coupes making the trek. One of them was a Z4 M Coupe -- a press vehicle that made the trek up from San Diego.
