I think you guys are getting the wrong idee about the E30's, here's the whole story behind them.
we bought the black e30 as a convertable for R8000, the roof was missing, the body was badly damaged but the suspension and the engine was fine and we needed another pickup, so we changed it into one.
The yellow E30, I swopped a pc for the yellow one, it needed an engine, gearbox, bumpers and so forth, I had a toyota 3c turbo diesel engine mated to a bmw 318 gearbox lying around so I fitted them, I also bough the bumpers from the local scrapyard, problem was when I had that car i did not get a huge salary so I could not afford to properly fix it, but it was wheels and it drove without any problems, until the electrics gave in.
