Free money
This requires 2 PSPs and 2 copies of Gran Turismo.
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 figured out this trick, and after some effortless patience, I was racing with all the cars I thought I would never afford. Hope this helps.
