I just bought a 2017 Teryx4 with 5900 miles and about 320 hours. averages to about 18 mph. I don't have a history because it came from an insurance auction. It looks to be well maintained, oil was right spot and showed some color but not black, air filter is new looking, rear tires are new looking fronts about 3/4 tread. I was worried that 4x4 didn't work but cleaning the switch brought it back to life. runs great sounds great. Anything I need to look out for at this mileage?
