Bi-Polar finished the 1000 last year in a Prowler:
UTV Industry News: Arctic Cat Prowlers Sweep Baja 1000
Finishing first in the 634-mile race with a time of 27 hours and 57 minutes was a stock 2009 Prowler XTZ 1000 driven by Creagan and co-pilot Tim Wagner for the first 409 miles, followed by driver/co-driver Chris Fallon and Aaron Bahner for the remainder of the course.
Yeah that was pretty awesome for a stock Arctic Cat, they did what full blown race Utvs dreamed of doing.
