Secret Black Cars
The vehicle line-up in the used car showrooms is constantly changing. On the last week of the changing cycle--starting day 694--four secret black race cars appear in the showrooms. Two of the cars are in the Used Car Showroom I and the other two are in Showroom II, and they only appear for one week (Gran Turismo time). All four cars can be purchased for about Cr.8,500,000 total, which is an absolute
bargain for these sort of race cars.

Free Horsepower
When you buy or win a new car, take it for an oil change. After the oil change, your car's horsepower will increase.

Hidden Black Cars
On days 694-700 in the used car lots you can buy special black versions of:
1.Toyota GT One Race Car
2.Mazda 787B
3.Nissan R390 Race Car
4.Nissan R92CP Race Car
5.Honda S2000
6.Clio Sport V6 24V Race Car
To Buy them all it comes to roughly 9,000,000 credits

Licence Guides
To get a Blue (acceleration) and Red (brakes) Licence Test Guide simply push R3 during 3,2,1,Start. It shows you the best route to go and where to start braking. This only works on the B and A license tests and tests where there is no pace car.

Speed up B-Spec Races
While in a race in B-Spec mode, press R1 to switch to Race Monitor. Hold L1 + Right on the D-pad and you can make the race go up to 3x's faster. The only downfall is you have to stay on the Race Monitor screen in order to keep the race sped up, it switches back to 1x when you go to Broadcast View mode.

2022 Nike One Morse Code
If you look really close on the side of the Nike One, you can see a small area near the front of the car of morse code. If you go into photo mode, this will become clearer. The morse code is written backwards as to be seen correctly from inside the car. Spelled out, it is " www.Phil-Frank.com " the website of the Phil Frank Automotive and Product Design Company. Phil Frank was paid to design the futuristic Nike car specifically for Gran Turismo 4.

Speed up replays, and turn off BGM
To speed up your replays simply press down L3 and to turn off the background music simply press O.

Stay in same gear in Automatic transmission
When using the automatic transmission option, hold R2 to make your car remain in the same gear. This is great for remaining at a given speed through a corner, or stretching the top end of a gear for a little extra speed/performance.
