Well,
The ZZII is really nice. (I'm a fan of solid paint schemes)
The rgt is also good for that, but a few decals on a rgt lm wouldn't be bad.
The evo 5 is real nice since it has both sides of the front end opened up for venting. ( And it's symmetrical up front, so that's a big 👍 ) (no assymetrical venting and no odd license plate placement are rare on some of the evos... damded evo 6 tme )
The motor sport elise is awesome, which is rare among those cars since I am not a fan of most racing color schemes. (there are some in gt3... Im getting to them.)
The jag race in the all white is real nice looking.
The denso's white/burgandy/orange? is perfect, and the castrol is also on key.
The arta and raybrig are both great.
The calsonic...

The oreca viper is alright. (would love to have the green/white viper from past games or the taisan jgtc viper in black/red.)
Anyone notice a trend in my picks... A fan of solid color cars, that I am.
There are a bunch I missed, I just know it, but who cares.. this is a old thread. (I think) It's almost like this is one of the few threads that allow for discussion of gt3 based concepts... just talking about gt3 can be hard on this board when there are no continuing discussions.
