Finally this month we bring you coverage of Sevenstock 13, the aptly named 13th annual gathering of all things rotary or Mazda related, at the company's North American corporate headquarters in Irvine, CA. Billed as the largest rotary show in the world, Sevenstock is more than all three generations of RX-7. Rotary trucks and sedans, previous and subsequent RX-badged models (2, 3, 4, 8), and even a few rotary-swapped Roadsters (and, sadly, LS-swapped RXs) trekked from as far away as the East Coast to attend. Factory-backed Mazda race machines could be seen throughout Vendor Alley, between the show and an RC car challenge and demo, and even some vintage Le Mans and Formula cars were displayed just to keep it reals. for the rest.
