Grand Theft Auto 2 Easter Egg - Get Seven of the Coolest Cars in the Game! (Tank, Fire-Shooting Fire Truck, Etc.)

On commercial district (that's the 2nd level of the game) there are three or four blue sport cars with a number on them. They do not go around town; they're just parked there.
What you need to do is find two of these cars. I'm not sure how to get to all three or four of them, but the two easiest I know are (don’t worry, you only need two of those cars anyway):

1) In the SRS (Scientist's) part of the level, there's alot of boxes, right? Right. Find a place with 7 of them, and they're a little apart from each other. Get on the first one using the stairs, and jump from one box to another until you get to more stairs. Go up those stairs and find the car.
2) In the Redneck village, you know where the red phones are? The one that give you the hardest missions? Well, go up there with a fast car. Go right, cross the bridge, and you'll see a wooden ramp. Gain some speed and jump that ramp. You'll find yourself on a small piece of land with nothing but the sports car on it. Get inside the car.

Once you'll get into the first car, you'll get magically teleported to "Wang's Used Cars". There will be nothing there. Now, go find the 2nd car!
Once you get into the second car, you'll get teleported to "Wang's Used Cars" once again, but this time, there will be seven (7) of the coolest cars in the game waiting for you!
4 sport cars, 1 army car, 1 FBI car (with a machine gun in it), one Fire Truck which shoots FIRE instead of WATER, and of course, the almighty TANK! (Note: Unlike the "Kill Frenzy" tank, once you get out of this tank you can actually go back in!)
And to prove all of this, see this screenshot: http://www.hypertony.co.uk/gta2/gta032.jpg

Now, pick your car and do what any normal person would do... GO ON A KILLING SPREE!!!

Love, BR.
