Unused Content in Gran Turismo 3

Gran Turismo 3 is quite well known in the Gran Turismo community for having a lot of unused content, most of which was removed toward the end of development.

Unused Cars
The most amount of unused things in Gran Turismo 3 are the cars, with at least 20 confirmed unused cars in the game's code. There are however evidence of other cars possibly existing during development.

Unused cars in the Demo


In the second Store Demo for Gran Turismo 3, a regular version of the Ford Mustang SVT Cobra appears. It is not the same SVT Cobra R in the final game because of different front bumper and rear wing designs. It can be seen in this video which tests the demo version of Trial Mountain II, however the model is clearly unfinished as the wheel axis appear sometimes while the car is turning, and the shadows aren't correctly rendered.

Gran Turismo 3 Scanning Day
At some point in the game's development these images surfaced of Gran Turismo 3's scanning day inside a copy of {magazine needed}. They feature some cars that never appeared in the game, which could possibly imply these cars were originally intended to appear in GT3. The images to the left show these cars that never appeared in game. These cars include: A regular version of the Citroen Xsara appears here as well, however this one may have been used for the scanning of the Xsara Rally Car which was included in the final game.
