Even if your batteries are free (they have a scrap value of $7-12 each) you still need cables and lugs to make your own cables to connect batteries together tend to be $4 each or more and you need two per battery, 6 volt batteries tend to hold up better then 12 volt batteries but for a high voltage system you would need alot of 6 volt batteries.
Then you need the copper cables at a few bucks per foot, someone with a $2,000 crimper to crimp the lugs to the cables, battery boxes, a controller (more lugs and cable to connect to the controller and motor) you need a motor, but lets say you can get a motor for scrap price, scrap price for motors is around 25 cents per pound and for a vehicle that size you might end up with a 100+ pound motor, but who is going to sell you a motor for the price of scrap?
Then you need controller, you can make your own, or buy one, ones that work for a high end golf cart tend to be in the $400-600 range and for a full size electric car $600-$2,000? you could spend more if you want to burn tires.
of course all of this is assuming that you are the kind of person that can live with a very low income, who grows and finds food and can make a $100 car last many years.
