Over 8,000? Come on, who's going to believe that. I bet it's all soaked with oil and trail debris, and looks like a pile of trash going down the trail. Probably has some branches wedged in somewhere, hence the name brushhog. Maybe you should stick to lumberjacking rather than snowmobiling.
Yes 8,000 and it may be a bit oily under the hood but I would rather have it look oily and have fun than look all pretty and just do a bunch of work polishing and washing it. And over the course of 8,000 miles, it has hit a few branches in its time.
