Hi guys, today i bring you a new update of what i've been doing, it's an audi quattro s1, i've been working on it for a while, this model had some things that the original model doesn't have, you can see that i rebuilt the back part, changed some textures and edited them, and made the speedline wheels that the original one has, also i added a turbo. i have edited two versions of this car, i still have some things to do.
