GHOST CARS!
If you go to a certain place on island 2 (looks a bit like 2 horse shoes) glendale's will come at you, trying to kill you.
Until you find the ghost car, it is completely invisible and is found in between 2 trees.
But if you get in one of the glendale's (they will be a bit dammaged) and use the heal car cheat.
(R1,R2,L1,X,LEFT,DOWN,RIGHT,UP,RIGHT,DOWN,RIGHT,UP) while in the car, it will not heal!
Theres loads more info this game, right here, with some cheats and tips, answers and Grand Theft Auto: San Andreas walkthrough.
