Grand Theft Auto 3 Hints

Use the tank code (Circle (x6),R1, L2, L1, Triangle, Circle, Triangle)
Get alot of tanks and park them all in a line across the road where the street race starts. Go and get your car, and go to the markspot to start the race. Then, the other 3 cheetahs will be blocked, so go towards joey's, and find your way to the first marker. Then keep on racing, you will get $10,000 !

Okay, In your garage at your hideout, your only allowed 2 cars
in your garage. But, i squeezed in 6 cars!
When you already have 2 cars, park a car infront of the garage
door so that the front of the car is touching the garage door (this
cheat will fix that dent) and get out. When the door opens, quickly
jump into your car and drive it in your garage. My garage now is full,
so you can have a maximum of 6 cars stashed. Limos count as 2 cars.
