I checked one out about 4 months ago, purely out of curiosity. Seemed to be a very well built machine. Can't even remember which model I looked at, but I'm pretty sure it was equipped with a diesel. Sorry, not much help to ya. Go to their website to get the specifics & check out the online reviews. Heck, see if they have their own forum & do a little digging there as well. Good luck & keep us posted!!
EDIT: I was looking at a UTV side x side, not an ATV.
