There are other vehicle construction systems available for Fuzion, used to build everything from tanks, to jets, to hydrofoils.
All vehicles are real vehicles.
All modifications are real modifications. All prices and weights are real. Performance and vehicle specs are real. Vehicles are not built from the ground up, rather, an existing model is purchased and then modified. Just remember, it's a 106 miles to Chicago, you've got a full tank of gas, half a pack of cigarettes, it's dark, and you're wearing sunglasses.
