Hi, I'm a 500 HO EPS owner. I like it a lot, never had an issue getting warranty work at all. I haven't had to take it to the shop but I think 3 times.
1st time was for the fan, no issue getting it fixed, and they improved it. That was the same time I blew a radiator hose, Fixed free. The replacement hose had a pin hole leak where some idiot put a hanger through it. (Small like a clothing tag.) that was my second fix. 3 was a nut backing off in my CVT. They fixed that and also replaced the belt because it might have a little undo wear. Other than that, I haven't had any major issue.
Big kicker is that you can't get much better for the price, my wife is comfortable on the back half of the seat, the extra 8" of chassis makes a little more comfortable ride.
Great thing is that when the wife isn't with me, I can stretch my self to the back as well.
We've easily had over 800 pounds riding on it, and it just moves.
One thing that I found later since I got some speed on the 500, I kind of want to upgrade to the CForce 800, but the 500 suits us well, and it's safe.
Happy trails ahead
