Truthfully this is a good market and trade values are high due to low new inventory, I got $4200 in trade for my 2016 sportsman 570 atv, bought it for around $5500 new, didn’t seem like a bad deal to me, talk to a few dealers.
That said, had I wanted to deal with it probably could of sold it outright for $4500 but might of taken a month or two, wasn’t worth the hassle to me.
