Fastest production truck in the world at the time of its release. The follow-up to the Buick Grand National Series. Based on the Chevy S-10 platform. 4.3 V6 Turbo. Faster than many supercars out of Europe. I had the great fortune to SIT in one once at the CES in Las Vegas in 1992. What a treat. It was the perfect vehicle. Basically a Grand National with more comfort and all-wheel drive. GMC could churn out some great vehicles, the problem was they were all limited editions.
