Gran Turismo Cheats for PSP

Before you start the game, and if you have the latest version of the PSP update, go to the Playstation Store. While you're there, go to Add-ons and search Gran Turismo. You should find only one add-on that says: Gran Turismo PSP Car Pack. Download it for free, and in Gran Turismo when you start it should say five gift cars have been added to your garage. There you go- Lamborghini Countach LP400 (SP model) '74, GT by Citroen (SP model) '08, Nissan GT-R SpecV (SP model) '09, Enzo Ferrari (SP model) '02, and Bugatti Veyron 16.4 (SP model) '09.

After every 70 days, the dealership cycle starts over again. For example, day 71-72 will have the same dealership cars as day 1-2. So if you wanted a Bugatti Veyron, which shows up on days 45-46, you would need to wait until day 115 until you can have a chance to buy it again.

So far, there are three cars on Gran Turismo that I regret getting, because of problems with the 1st and 2nd gears.
1: Ford Focus RS
2: Honda Civic Type are
3: Nissan GT-are Spec V

(This takes time, but is effortless.)
If you have access to 2 PSPs and 2 copies of Gran Turismo, simply enter into a garage and create/join a race together. Pick the fastest car in the (primary) garage. Go to the Test Ring track, and set the laps to 99. The higher the laps, the bigger the prize money. Start the race, and with the primary car, pause and set the game to autopilot. Come back after a while and collect your free money. Go shopping for a faster for a faster car. The faster the car, the quicker the race, easy. After you have more money and cars than you need, you can do the process all over again with the other PSP, or (while the game is in play) swap the memory sticks, and save the money onto the other card as well. I know it can be frustrating to take the time to e..

Simply create and enter a garage together for a race. Set the track to the Test Ring, and the laps to 99. The more laps, the more prize money, easy. In the (primary PSP) garage, pick the fastest car. The other car doesn't matter. Start the race. Pause the primary PSP and set it to autopilot. Come back to collect your free money, and start again after buying a faster car. Keep doing this until you have all the money you think you need, and then you can start all over on the other PSP, or (with the game running) swap memory sticks and save the money game to the new card. Some games can be frustratingly hard to get to the bigger, better things without cheats or codes. Especially when there are no codes available. Thankfully, I fi..

Race on the Driving Park Test Course on difficulty level"S" for 24 times 2 laps each and you will make about 4,000,000.This is much quicker than doing the 99 laps that will make you about 1,000,000

Here is hoe to get more than 1,000,000 credits easily! First off, get the Pescarolo C60 Hybride Judd Race Car '05. It will set you back 4,000,000 credits, but it is worth it! Once you have the car, go to the Driving Park Test Course - Forward, and click go. After it loads, go to event options and change the number of laps to 99. This should put up the 1st place money to 1,071,000 credits. Now get a piece of tape and put it over the x when the race starts. You can also use a clamp or something, just as long as you have the x held down. Now your car will just drag around the wall, but it still beats the other cars! Wait a couple hours and you will have won over 1,000,000 credits! It works for me, hope it does for you too! Happy gaming!
