Cut it up then take it to a scrap yard, thats what i did with my old s13

rip-saw/sawz-all's work wonders with the right kind of blade, also if you have access concrete saw and dont mind going through a blade they work good too. or air powerd die grinder with a larger cutting wheel, plasma cutter.. ect ect not to hard to cut up a car, takes about 2 hours with 2 people depending on the tools being used.
