Carbon had the best customisation out of all the NFS games. You could add a different front bumper, rear bumper and skirt and modify parts of each of them with sliders, so it was like sculpting your own body kit (number of styles were limited of course). You could also buy full aftermarket body kits (which I mostly ended up doing because the complete kits still looked the best).
Carbon lacked in other aspects though, like side mirrors and other small details.
