Participate in the Super Speedway Endurance race with an F1 car. To finish the course faster, instead of using the walls as guides, try to make the turns. If you bump into the walls it will not be a problem. Pit every ten laps and you will easily win a car that is worth a lot.

Win first place in the Grand Valley Speed Way endurance race . When you select a car for winning, look for the R30 GT-1 Road Car. If you choose this car, you can sell it for 550,000 credits. Since your prize earnings are 400,000 credits, you will get a total of 950,000 credits for winning the race.

Go to Rally Events and select Tahiti Maze. Choose to play against the rally car. Start the race and your opponent will crash into the wall and will not be able to move from that location for the entire race, leaving you to win.

Buy a Supra Rz, Skyline GT-R V-spec, or Suzuki Escudo and tune it to the max. Enter the Like The Wind cup and go to "Settings", "Drivetrain", "Gearbox", "Autoset 48", then start the race. The Skyline will go 257 mph, the Supra 254 mph, and the Escudo 295 mph.

When you have a fast car go to Special Events, then the Sunday Cup and choose Tahiti Road. Race the slow vans to get 3,000 credits.

When you first start out with 18,000 credits, go to the car dealer and buy a Mazda (not the one with wheels that look like flowers). Once done, race in the Beginner league then complete all three races in the Sunday Cup. Keep doing this repeatedly until you get enough money to tune up your Mazda. After you tune it up, test it and make sure it goes 174.1 mph and accelerates quickly. Then, race in the Beginner league and enter the World Race and race in the Super Speedway to get 10,000 credits. REMEMBER: You will race rally cars in the Super Speedway. Tuning up your car incorrectly will cause your car to spin out of control when turning.

First buy a daihatsu curore then go to sunday cup. Complete that and sell the winning car. Keep doing the super speedway track till you get 25000. Then go to mitubishi and buy the cheapest Lancer. then tune that and race it in the evo cup. By Michael Phillips age almost 11

Ok, firstly get the Suzuki ESCUDO Pikes Peak Version, boost the horse power by tuning it to turbo kit 4, then go to Endurance, and pick the very last one, Super Speedway. Go enter it, until you have finished it then they will give you loads of cash. And you also could win a F1 Race Car!!!

Buy the PT cruiser and enter into the Sunday cup. Then, tune it up as much as you can and enter the PT cruiser into the Clubman cup. Finally, sell the 2 cars you got as a prize. This is a good way to start the game!
