i have an 07 420es and love it. The es does hang up sometimes when it is cold but it only takes a few minutes to warm up and then it works great. I have 25" bighorns on it the stock tires are crap in IMO, just not good in snow at all. I hit a tree with mine and bent the crap out of it and the suspension, frame and all the important stuff was good. rad took a beating and didn't leak at all....I was shocked at what it can take and still keep going. picture of it after the tree and after about $500 in parts.
