but guy the how did this(look some page before) use vray or brazil with hdri i think, thats all
... here is your picture in 1280*1024
The only problem is with the GTL is this game use the MK II! For the difference please see that page: http://www.racingicons.com/gt/finish.htm ! There isn't too much differents in these too cars, but there are some little details, what i want to make, and i can't see these on a low res picture! So if i can't find pictures i make the MK II, but my aim is the MK I whit every details!
if you send me the scene what you want to use, i can make it for you(i need the .max or .3ds file and the textures)
but on that site you can find a complete VIDEO tutorial for modelling a car - http://www.3d-palace.com/ - enjoy! 
can you do it in 2048*2048? and i render it for you!
