Gran Turismo

Gran Turismo is a racing game developed by Polyphony Digital and published by Sony Computer Entertainment on October 1, 2009 for the Sony PSP.

The game featured a single free DLC that gave access to 5 new cars. The PS Vita release of the PSP version allows to download the DLC, but to be able to get it on the original hardware a Sony PS3 is needed (see below for details). Unlike games, DLCs on Playstation 3 are region locked, meaning that PAL games are not compatible with the North American downloadable content.

How to obtain
The DLC can still be obtained on the PS Vita (PSP) release from the Playstation Store or, on the PSP, by purchasing the PSP version on a Playstation 3 system and then transferring the content on the handheld console.

A guide on how to transfer content can be found here.
