Not for a Fiero, but using 20' of 2x12 and eight heavy duty casters from Home Depot I made a totally ghetto but totally functional car dolly for moving around cars without suspension. Total cost was around $80. It could have been cheaper, but I used the beefiest casters Home Depot had since sometimes I end up moving cars in excess of 3000lbs. For a mostly stripped Fiero, much cheaper casters could probably be used.
