Buick Syclone. Privately owned.
Codename “Lil’ Red Truck”. During the Syclone’s development, there was a debate to introduce it as a S10 version. Chevy wanted it while GMC refused it….after all, they were in charge of the concept and platform. Before the idea was completely squashed, the development team threw together this 1989 S15 complete with custom 16″ steel wheels with correct offsets to accommodate the Safari AWD driveline and installed a full-on Syclone drivetrain. The truck had a bench seat, manual windows, an a column shift. The last known whereabouts of this truck was in Virginia in 1999 with around 222k on it!
