Something to consider is, where will the batteries go in a small car? On a FWD the motor and transmission are under the hood, taking up battery room. Not a problem if you are comfortable with batteries in the passenger compartment.
A RWD of sufficient size (I intend to do an extended cab minitruck) will let you put the entire motor inside the transmission tunnel, leaving the entire underhood area for batteries or what have you. What I really like about doing a truck is I can mount batteries under the hood, and along the framerails of the truck where the fuel tank is. Just gotta work up them bucks to make it happen. Kind of a catch 22 there, can’t afford to convert to an electric car because all my money goes to the gas man, if all my money wasn’t going to the gas man I could afford to build an electric car.
