A tweeked frame isn't the end of the world. Mine is a little bent but one of these days I am going to take it and chain it down to something solid and use come-a-longs to get it straightened out. Not that it is a problem now, though. The hood just doesn't shut straight and the fenders don't line up with the rest of the tub and it bothers me. It is to be expected really with this old of a small off-roadable vehicle.
It sounds like someone already got things to line up somewhat. Does it drive? If so, why get rid of it?
