Good idea, I'd love to add some vehicles you can purchase to travel around freely & not rely on public transport.
Some ideas for vehicles could be bikes,mopeds,motorcicles,cars,pickup trucks,vans,trucks or even a boat or a yacht.
Trucks to move around your biggest characters or even yourself around town sound really great, the bigger the person the larger of a vehicle they need. A blob needing a truck to be moved sounds about right.
