On PSN There was a Add on for Gran Turismo PSP released, this add on allows people to download some of the SP Model Cars. The add on Pack was slightly different in the US & the EU. The Arctic White ZR1 & Magmarot Red SLR were not made available in either (The ZR1 only available when getting the GT Entertainment Pack & The SLR was available in the US through Qore, but no longer is. In the EU the SLR is available through a Mini game on the EU GT Official site). The Black Veyron was made available to the US and not the EU (In the EU this is obtained with the GT Collectors Edition)
Ive made codes for all the SP Model car. With these codes you just need to enable the code and & buy the car, unless you already own a regular edition (Non SP Model) Then you can drive ANY SP Model you want..
The ZR1 or SLR code will change any ZR1 or SLR you Purchase into a White ZR1 or Red SLR as long as the code is enabled when you enter the dealership (They will say "SP Model", but the icon will be a regular color). When turned off & the game is reset the car will Stay as a Ghost in your favorites if saved to them, if not it will only appear in the car lot when the code is enabled.
You can enable 1 code or all of them at the same time, they do not interfere with each other.
This will also convert any AI controlled cars into the enabled SP Model (If a Veyron is one of the AI cars [or all three], when the code is enabled it will be the SP Model) So you can race 3 Black Veyrons with a White ZR1, a white ZR1 racing your Blue GTR R35, etc.
YOU DO NOT NEED TO BUY THE CAR IF YOU ALREADY OWN A REGULAR EDITION
If you already own the car in a regular edition, enabling the code will change it to a SP Model while the code is enabled.
DO NOT Use The Favorite (Car saved to Favorites List) of the regular model car (Not the SP Model) when the code is enabled (It will crash the PSP) When the code is enabled you can save the SP Model to your favorites and it will keep the SP Model on your Favorites List with settings for later use, Just make sure you use the "SP Model" after the code is enabled.
The codes are formatted for CWCheat (Tested on US Copy of GT)
