9 month update.....
My Axis 500 is still kicking. After hauling deer out of the woods during deer season to the first snowfall it's worked well. We had 6 inches of snow in the last few days and the wife and I took it out to play in the snow. It really does well with the regular knobbie tires one it. I could ride all the trail on my property in 2wd H...but it's more funner to crawl along in 4wd L. Pretty much can go through anything. I hauled 6 or 7 loads of firewood with it as well.
Having said that it's been in mid teens in terms of temps the last week. Hadn't driven it in a couple weeks and it started right up. The plastic gets somewhat brittle in cold temps. I hit a low hanging branch which cracked the roof. I also broke a tailight and cracked the side panel where the gas cap is. Oh well, stuff happens. When you ride narrow trails in the trees you're gonna hit stuff.
Bottom line, I'm still impressed with it.
