the only thing with turning into a Cab/Trailer in one means that alt mode would be totally out of sca... what, nevermind, this is Transformers we're talking about, carry on.

Might not be the G1 Motormaster we remember, but he's not the only Classics-verse character to have a pretty decent makeover - Kup, Perceptor, Windcharger (RTS version), Jetfire, multiple Optimii etc. While MM's deviation from the original design might be further than the others listed, I can deal with it, because it means I've got an affordable Menasor.
