Carmageddon 1 and 2 sites
The Carmageddon Fan Club is the best site I have visited with a good files section. It has quite a bit of "inside information" and other interesting things.
Crash & Burn Crimson's Crash and Burn site has a very good selection of cars.
Be Quick or be DEAD Very good car skins site well worth a visit
Carmageddon2 @ Gamers.com A very frequently updated carma2 site
BrainFrame Productions isn't strictly a carmageddon page, but it has some great cars and models. (3D cars, that is :)
C2CNFS (Carmageddon 2 Carpocalypse Now Fan Site)
