how about a dumper truck xD or possibly a JCB digger? maybe a space shuttle! or a rabbit shaped shell XD
the 2 odd ones i know exist that i like are the flat fronted lorry shell and the old manster jam bull head one (el toro loco AKA bulldozer) sadly i think the truck one is for FG 1/5th scales or 1/10th cars, and the bull head is discontinued
