Does anyone know a nice car game for pc which is moddable (freeware would be nice)?

SLRR. Old game, mod Support, controller and wheel Support.

Mods as in car mods or community mods?

Race ‘07 by Simbin

Rigs of rods

Everything is free if you want

Thanks everybody! Keep it up if you find something else. I will try those games ;)

Live for speed is really rather good, I love the physics of it

BeamNG Drive is pretty sick, definitely worth a download. It’s not free but it is still very cheap. It’s currently just a Beta, but if you buy the Beta you’ll get the full version for free.
