At the places where you can buy your cars (for example, BMW), you can find races that use a certain model of that dealer. This will unlock some of the bonus cars you cannot normally buy or win in a race. The cars that you get are very fast, and you can sell them for a decent price.

You can win different cars from series races that you have already completed. For some series, you are given the option if you would like to clear your current records. If you do this, you can race those courses over again to win another prize car.

Easy money:  After transferring your licensees and credits from Gran Turismo 3, buy the Dodge Viper GTS and soupe it up. Then, go to the Special Event races and compete in the Capri Rally Easy. After you win both races, you are awarded with a rally car worth 236,000 credits. Go back to the Capri Rally and compete in it again. You will be given the Same Rally Car. Sell one, and you will have 236,000 credits.

Buy a decent car like an Evolution (must be of Japanese make) and upgrade it as much as possible. Then, go to Japan and compete in the All Japan race. Each gold awards you 7,500 credits (five races), and all golds gives you 35,000 credits. You will win a 350Z race car at the end. get In the new 350Z and upgrade if desired. Then, compete in the All Japan race repeatedly. Each time you get all golds, you will get another 350Z that can be sold for over 318,000 credits.

After transferring your licenses and credits from Gran Turismo 3, buy a Civic Type R (EP or EK). Then. add mods to it to get over 230 hp. Go to the Honda dealer and join the Civic races in the One-Make Races. Finish first in all the race courses and you will be awarded the Mugen MOTUL Civic Si Race car '87. Sell it for 90,000 credits. Then, repeat the process again.

Once you win the Cadillac Cien from the two easy Citta di Aria races, and have acquired the IA License, go to the Normal Tsukuba Circuit Wet race. If you manage to win the race (which should not be too difficult in the Cien as long as you can handle driving on the wet road), you will earn 10,000 credits and a Mazda6 Touring Car worth over 93,000 credits (if sold).

Get any car that has about 400 hp and go to the Special Condition Event. Select the second race from the top. Defeat the CPU in both races and you will get a car that can be sold for 260,000 credits. You can also use that car to race in the same event. When prompted to clear the trophies, answer "OK". When you win, you will be awarded the same car.

After loading you Gran Turismo 3 game credits (100,000 credits) and A and B licenses into you Gran Turismo 4 game save, Go to Tuner Village in the lower left hand corner of the main menu. Select HPA Motorsports and buy the VW Golf look-alike, (2004 HPA Motorsports Stage II R32) for 31,870 credits. Exit from the Tuner Village and go to the Special Conditions Events icon. Enter the 2004 HPA Motorsports Stage II R32 into the Cost Di Amalfi race. Do both races forwards and backwards. This should only take about ten minutes with the 2004 HPA Motorsports Stage II R32. When you complete this event you will be rewarded with the 2002 Toyota Rsc Rally Raid Car, which has a selling price of 265,624 credits. Sell the 2002 Toyota RSC Rally Raid Car and enter the Cost Di Amalfi race again with the 2004 HPA Motorsports Stage II R32. You will be asked if you want to "Clear Records" from your previous races. Select "Clear" as your option. Enter the races again. Win both races and you will be rewarded with another 2002 Toyota RSC Rally Raid Car. Keep doing this repeatedly to get as much money as possible in the least amount of time. Within one hour you could have up to 1,650,000 credits. Keep returning here as your credits run out. Also, you will get an extra 10,000 credits for taking first place on both Costa Di Amalfi races. Also, the 2004 HPA Motorsports Stage II R32 can be entered into quite a few races very early in the game, so you do not have to waste your credits buying other cars.

Win a Chevy Chevelle SS 454 '70 from the American Muscle Car Championship (using a suped up Ford Mustang '05 recommended). Add a stage 2 or 3 engine setup then a supercharger to get 600 to 700 hp. Take it to the Classic Muscle Car championship and race using B-Spec. You can get a fast 10,000 credits because the race is only two laps (Laguna Seca recommended). Repeat this as many times as desired.

This trick requires some time. Once you can do it, this trick will give you over 890,000 credits in about ten minutes. You must have the IA license and the Mercedes-Benz CLK Touring Car. To get this car, you must acquire or buy any Mercedes-Benz car that will be fast enough to win the Legend of the Silver Arrow competition (go to Germany, then Mercedes-Benz, then One-make races to find the Legend of the Silver Arrow event). Winning the Legend of the Silver Arrow competition will give you the Mercedes-Benz CLK Touring Car. Once you have the Mercedes-Benz CLK Touring Car all the way fixed up to its maximum and the IA license, you are ready to start the trick. Enter the Deutsche Touring Car Meisterschaft Series race in the European Events. There are five races in this competition: Opera Paris, Mid-Field Raceway, High-Speed Ring Reverse, Nurburgring Nordschieife, and Fuji Speedway. You will not be doing any of the racing yourself, as you will instead use the B-spec Director's Mode on all five races. When you are ready to start the first race in the series, activate B-Spec Director's Mode. The race will now begin, and you will see the numbers one through five at the top of the screen. Press D-pad Right(2) so that it is highlighting the number "5", which signifies "Push" (the car will go as fast as it can). Once "5" is highlighted, press Triangle to put the car in overtake mode. Now that "5" and the little symbol next that number at the top of the screen are both highlighted, you are all set. Press R1 so that you are in Monitor Mode. While in Monitor Mode, hold L1 and press D-pad Right(2) so that the race will go by three times as fast. Do the same exact thing for all five races. It should take about ten minutes for all five races because you are in B-Spec mode. You should finish in first place always if done correctly. After all five races you will have 75,000 credits for being first place, plus an additional 75,000 credits for being the overall champion of the series event. On top of those 150,000 credits, you will also be rewarded the Mercedes CLK-GTR Race Car, which you can sell for about 743,000 credits.

Get a good rally car. It does not need any special tires. An Evo 8, MR is recommended. Then, go to the Special Conditions Events. Go to the second race in the event, known as the Capri Rally. It is fairly easy, but you need a A-Spec: National License. Once you win both races, you will get a Toyota RSC Rally Raid Car that can be sold for 265,624 credits. You can then go back into the same race, clear all your records, and win the car again.

This trick requires two memory cards. Use the first memory card and buy good car for 10,000 credits or under. Trade the car to the other memory card and buy upgrades for it. Delete the block on the first memory card and restart so that you get 10,000 credits again. Trade it back to memory card one and repeat the process.

Extra horsepower:  Give your brand new car an oil change immediately when you get it (before driving it). It will usually gain between 5 to 30 hp.

A-Spec Points:  If you enter a race, and all the cars are very low end and you have a high end car, you will get very minimal A-Spec Points awarded and vice versa. For example, enter a 800 hp car into a race with the other five cars having between 200 hp to 300 hp. You will probably be awarded only 1 A-Spec Point if you win the race. Conversely, if you enter a 800 hp car in a race with five other cars that have between 750 hp to 900 hp, you will be awarded anywhere between 50 to 100 A-Spec Points.

Easy Nurburgring 24 Hourr Endurance Race win:  Obtain the 2004 Ford GT LM Race Car Spec II (the white and black car in the opening sequence) from the Professional Events-GT World Champion race (ten races totaling 136 laps on ten different tracks). Buy everything available for the car, most importantly the Super Hard Racing Tires (R1s). Set the Auto Transmission feature to a value of 18. Equip the R1 tires and get ready for at least twelve hours (of sped up time) of hell. You must do this race in B-Spec mode with the 2004 Ford GT LM Race Car Spec II in order to guarantee a long hard fought win within thirteen hours real time instead of twenty four hours real time. In B-Spec mode, you have the option to speed up the race by entering the Race Monitor Screen by pressing R1. Then, hold L1 and use the D-pad Left or D-pad Right to go from real time up to three times normal speed. At the beginning of the race, set the auto pilot to a value of 5 (Push) and turn the overtake feature on by pressing Triangle. Once you get ahead of the pack and have a decent lead, turn off overtake and set the autopilot to 2 (Cruise). You should only have to pit every three to four laps. Get everything every time that you pit (tires and fuel). Set the autopilot back to 2 (Cruise) once you leave the pit. Continue this strategy until the end of the race. This will net you a Formula One car.

View ending sequence:  Win The Gran Turismo World Championship in Professional Events.
