I dont know if you will get 3K....kinda rough shape for only 1500miles.
Plastic looks like junk....the rear swing arm is all rusty and nasty looking...With only your pictures to look at I'd say $2500ish. You may get 3. I can't see where it's in terrible shape from the pics Mack? What do you see that I'm missing? I can't remember the site, but I think its Kelly Blue Book that offers estimated values for ATVs. This along with your local market will (what other like quads are going for) will be your best indicator what to ask.
