The Mazda2 isn't too bad in this game. I laid down some decent times in the C Class FWD rivals. I'm pretty active in Forza and have a time on damn near every event there is so feel free to add me for times comparisions and so on.
I downloaded it from the Storefront. After doing so, I learned that with downloaded vinyl groups, will "lock" the car and it will not be usable in certain online modes until the vinyls are removed. So I took it upon myself to make my own vinyls, and I gotta say if you've never made one from scratch, it's a test of patience.
