I'm not sure you're going to find one like you're hoping. I'd searched for a while for something that would just have my motorcycle like the one above (that didn't cost a FORTUNE).
I finally found one that is custom built and should do the trick ASSUMING my Mini Cooper will go onto the dolly section without mangling the lower plastics.
would one of the stackable units work?
Like this one? It can't be cheap, but might be the only thing that gets what you want.
