I am looking at buying an RMX250 in good shape. It runs good, has good tires and brakes. It is basically an RM250 with a headlight, tail light, and off road gearing and suspension. The price is 0. I can only afford it if I can get about what I pay for it in the late summer before I start college again. Is it worth at least 0?
