The junk yards off Jalan Bendahara in Ipoh have got lots of ex govt vehicles. I've seen plenty of land xxxxxs, stonefields, volvos, mercedes trucks and even a SIBMAS APV recovery vehicle. Dunno if they're willing to let for for cheap or not.
usually it will be sold by weight of steel (timbang kati)
continental cars are super duper heavy, so it will be around 1k-1.5k.
use small light cars.... but, it will still be costly. i know a good running volvo being sold for rm500 lol!
