Happy gaming!

Here is a step by step guide of how to get 9 King Cars!!:

1.Go to the code entry section on the main menu of your career and enter the code 'UNLOCKALLTHINGS'.

2. Go to the career map and all of the levels should be unlocked.go to an eaysy level and do 1 race, then leave the race day. Now in your Garage you should have a dodge viper, the car you start with, a chevvy, and a GTO.

3. Go to Nate denvers Challenge. Use the dodge viper and beat him.

4. Go to Aki Kimura Challenge. Use the gto to beat her. ( I bought a lotus elise to beat her. Only $90,000.)

5. Then go to Karol Monroe challenge and use a really tuned up rear wheel drive car to beat her as there is a wheelie competition.

6. Then go and beat Ray Kreiger with something with really good acceleration and
Handling because he is fast and the tracks have loads of bends.

7. Now go back and do the challenges before each king. When you dominate it the king will come up to you and race you again.

8. BEAT THEM ALL AGAIN AND YOU SHOULD HAVE THEIR CARS DOUBLED!!!!!

9. If you can't beat them and need better cars,get loads of cash by using the 'UNLOCKALLTHINGS' cheat and do a race [easy], go to the garage and sell the cars you get, save the game, and reset your PS2.

10. Keep repeating until you have lots and lots of beautiful cash! Happy cheating!!

Enter the "UNLOCKALLTHINGS" code. Exit to the main menu, reload Career mode, and you should now have the Nissan 240 SX, modern Pontiac GTO, Chevy Cobalt SS, and black Dodge Viper SRT 10 in your garage. Sell those four cars to get approximately $90,000. Then, save your career, and reset the game. Load your saved career. Enter the "UNLOCKALLTHINGS" code again. Exit to the main menu, reload Career mode, then go to your garage. The Nissan 240 SX, modern Pontiac GTO, Chevy Cobalt SS, and black Dodge Viper SRT 10 should be in your garage again. Repeat this process as much as desired and WHAMMO! Cash money.

On the cheat screen enter cashmoney for 10'000 extra cash

When you are in your career you can go to a section called codes what you do is type in cashmoney which gives you 10,000 and then safetynet it gives you 5 repair markers.
