Unless I'm really tired and you guys are aware of this already, it's been done before:
Laughlin/SCORE Desert Series Baja 1000, they also clinched the overall Class 3 title for the third consecutive year. The Sportage, driven by off-road champions Skilton and Curt LeDuc, also claimed the 1999 Class 3 championship by winning its fifth race of the six-race series. Skilton drove the Sportage to Class championships in 1997 and 1998.
The Sportage beat out seven Class 3 competitors that included a Nissan Pathfinder, Isuzu VehiCross, Jeep CJ-7, two Isuzu Amigos and two Ford Bronco IIs.
