Maybe not too stupid then, I`m thinking of a trials type sidecar,
just looking at the Supersoco machines, around £3k or under for a nearly new, no idea how a sidecar fastens on but I assume it needs a front downtube ? having said that vespas don`t need one, the Supersoco has a cover over the front so can`t tell, there is a dealer nearby, might go for a look next year..
