Easy money
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.

Free Repair Markers

Preventing points deducted for damage
Normally points get deducted for wrecking your vehicle when you participate in any career race. However, if you race in any one race and wreck your car, do not repair it. Any other race that you race with that car will no longer take points off for damage. By doing this, you can get the full 500 points toward dominating an event. Note: This only works while in the same car previously damaged during an earlier event.

Recommended dragster
The Toyota Supra with all Level 4 performance parts can do the quarter mile in under 7 seconds if tuned properly. -From: Barry Woods

A really good dragster is the Dodge Challenger R/T. The car runs 7.6 seconds in the quarter mile fully upgraded. If you make the rear shocks stiff, the car will stand on the rear end all the way down the track, and will do over 1,000 foot wheelies. If you make the rear shocks soft, you can run 7.6 seconds in the quarter mile and not have to worry about the front end lifting up. Some tuning will be needed, and knowledge of cars will definitely help.

A good dragster is the Nissan 240SX. The first chance you get, choose the 240SX. Put on all the best performance parts you can afford. Remember, you need a lot of speed and traction. After you start setting new track records, you will be invited to race Karol Monroe the Drag King.

Defeating Ryo Watanabe
Use the following cars to defeat Ryo Watanabe. Upgrade all cars with Level 4 performance parts and max out the aerodynamics. Note: Bring lots of Total Markers to Race Day.

Grip: Pagani Zonda. Use a "Free Car Marker" for this car, if available. You can also use this car to defeat the Grip King.

Drag: Ford Shelby GT500 or Chevrolet Chevelle SS. Do not do anything to the aerodynamics of the Chevelle. You can also use those cars to defeat the Drag King.

Drift: BMW Z4 M Coupe. Even though it has low stats, it is a great drift car. You can use this car to defeat the Drift King. Alternately, use the Mazda RX-7 if you have won it from the Drift King. It already has all Level 4 performance parts; all you have to do to it is increase its aerodynamics.

Speed: Ford GT. You can also use this car to defeat the Speed King.
