Bought my new '18 Teryx4 LE about 18 months ago.......
3300+ trouble free miles at this point....changed belt & plugs at 2800 miles
Easy to service....large 4+ quart oil capacity compared to most 2-3 qt in others
Three year factory warranty..opposed to 6-12 months with other mfg's
None are perfect..some quieter than others..look at your needs and wishes
Buying new ? Biggest option I suggest is full glass DOT vented windshield...buy once/cry once
