I loved the M.A.S.K cartoon as a kid, and of course the toys too!
My favourite was the Jack Hammer Ford F150, which converted into a tank like armoured vehicle, with a spring loaded cannon on the back and the hood would slide up to create a bullet proof cover for the windshield.
The driver was Cliff Dagger, a muscle bound thug.
I always thought M.A.S.K would have been cooler if it was in scale with Gi Joe, so here is my update.
