I bought a Pioneer 500 in 2017. Great Machine. Never had an issue.
I'm on my 3rd Ranger, and ain't been able to hurt one yet. I did break a front axle on a 1000, but it earned it. My new one is a 2020 570 Full size crew. I've give the poor thing plenty opportunity to break something, but it just keeps digginI would Buy whichever I find first. My Polaris Ranger has almost 7,000 miles on it and Nothing ever done to it.
