you win the 240ZG in the NISSAN races - 'Z' Cup, or whatever its called.

Japan - 70's Classics race wins you the KPGC10 GTR! very cool. there's white and silver available

the KPGC110 GTR turns up in the 80's used car lot - eventually!. in white, red, and silver definitely my favourite old school car!

there's other cool cars like:
1600SSS rally car
240RS rally car (and road version)
other old school Skylines like a Prince GT-B
and the old Silvia and Sports 2000's from the 60's

I know there's prize car and full car lists out there on the net if you want to google them. and even lists of what cars are in the used lots on each day - so you can find the C110 GTR for example.
