Welcome to OldMiniBikes:thumbsup: A great frame design maybe early 80s through 90s and good minibike to have. Yerf Dog made a similar frame but not as cool a lines. As with most things it's worth what someone or even you is willing to pay. I like to stay under $150 as a purchase price for a running minibike, that's what one is worth around here. And we don't do appraisals because it sets a dangerous precedent, good deals go away since perceived values are a click away and prices set accordingly. Ebay does this already and that sucks bad enough we will not join in. You should buy it of you think it's priced reasonably enough, certainly a well loved one with a rototiller briggs fiver powering it looks like. I'd love to have a chance to buy it locally in my price range, it would become my daily rider.:thumbsup:
