I used CS3 trail and its realy good i must say!

the stripe edits for the Maserati are awesome, great edits Bright_K

Nice work, the tire smoke on the back of the hummer looks REALLY good

Yeh they look right good, the neons aren't that bad lol well nice edits

Thanks, but i do still think the neon one looks utterly stupid lol i added some more new ones aswell

There nice, well i dont see much wrong with the neons

i like the ford gt

I'm liking the maserati with faye valentine on it:-p
