This is a summary of what I think we discovered so far guys (in GT2 & GT3)
Lets start with the GT2 demos:
- Montecarlo; it's Cote d' Azur with unfinished scenary and textures with the invisible walls. Me, Xenn, & Mattj55 from youtube all made videos with that course involved.
- Indi; it's a made up oval track based off Indianapolis Motor Speedway, but not the real thing since there's a lot of vegetation and a couple of tunnels around the course.
- Beta versions of a lot of the courses that are in GT2.
- Rome Short had proved in the demos to have been taking place in the sunset. That explains the screenshot of the red Ford Mustang I found once on google images that was on rome.
- Tahiti Safari Course; basically beta Tahiti Dirt Route 3 with different scenary and textures. The track has also less room to move around in as well as a shorter main straight.
- A bunch of beta license tracks and other license tests that have been cut before GT2's final release
- A bunch of hidden cars have been found by Xenn (check this url:

- Not just those cars, but these found by each of us:
*1996 Dodge Viper GTS
*1992 Dodge Viper RT/10 (both vipers had were updated in the final to their more modern counterparts)
*1997 Dodge Copperhead Concept LM(Concept Car) had it's original design from GT1.
*A lot of Toyota Altezza placeholders
*A lot of cars had different color selections than the final such as the Ford GT90 coming in 5 colors, Renault Clio V6 coming in yellow & silver, & Lister Storm coming in 7-9 colors.
There has been some great hidden content shown through early screenshots of GT2:
- Nissan R34 skyline has been seen on SSR11
- Mercedes Benz CLK GTR Race Car '98 was almost in GT2 as it was shown on Gamespot in action on Tahiti Road.
- A few other cars have shown to be almost in GT2 from a poster (somewhere on this thread I think):
*VW Polo G20
*VW Polo '98 (In the final GT2 as a hidden car, shows up in the Event Generator sometimes)
*White Mini Cooper Rally Car
*Prince nissan skyline GTR (I think it was called that)
*Audi A4 Avant (Xenn has posted a screenshot of it a few pages back)
Gran Turismo 3 Demos:
- Xenn has shown gameplay of a Ford Mustang SVT Cobra '99 on Cote d' Azur
- Special Stage Route 11 had the GT1 layout at one point
- Unfinished, figure 8 course
- A big, circle course for license tests probably
- Vector M12 was almost in GT3
Gran Turismo 3 Secrets:
- Porsche 911 GT3 (996) is hidden in the game
- Lamborghini Diablo GT1 is hidden in the NTSC version, available in the Japanese version, and was in the Pal version hidden (with a Daihatsu Mira Placeholder)
- Lancia Stratos & Stratos WRC were both hidden in GT3
