It sounds like your vehicles all share a strong outer body.

As for my grandfather, when he was younger he rounded up his classmates from the Royal Academy and some others who were interested and formed "Class M". Since our parents were always worrying about him doing something crazy, they'd drop my sister and me off at the Town Hall. But Noelle and I ended up helping out instead.

Grandfather always did like to be the one in charge, but it'd usually take all of us to finish the job. He's gone now, though.
