this is a ridulous post. a good condition, very clean LTR wont see below $2000. this one seems like a fair/good shapr quad and i think is priced fair. $600? thats a joke. try to find a decent, running LTR for that cheap.
good luck with the sale, man. LTRs are one of my fav quads ever. i used to race them and i thikn they are sweet quads, especially for the time.
