I heard from my friend that there are 1st and 2nd generation mini-z\'s. He said the difference was that the 2nd generation is more detailed and you don\'t have to stick any stickers on. And also the evo comes with mesh on the bonnet not stickers.
For example te BMW Z8 he said it was 2nd generation because it is really detailed and it comes with exhaust pipes.
Is this all true??

The first few bodies skyline and wrx have stickers for headlights and other things. But they dont look so bad, just a sticker behind a clear lense, you could paint it chrome instead of the sticker... ;)
The Second Generation are:
S-2000
Modena
Z-8
Altezza
Porche
Viper
and maybe the two mercedes.
They are also more durable, painted nicely, and there are no decals except for the ones that come pre-done on the license plate.
i just got the vw beetle body and it is much nicer than my original wrx body. i also have the toyota vitz and the silver mercedes, they are all much nicer than the original!
