Nothing at all. A modified car is more expensive to fix as the bodykits cost more and are harder to get than standard parts.
There is usually a special paint job involved as well which can be a nightmare to match up. The modded car is more attractive to thieves and vandals (its - not me this is a statistical fact). Sometimes cars suspension and wheels are not set up properly and the car is more dangerous to drive or harder to handle than the standard car that the insurance companies rated the premium on. So your not more likely to have an accident but you are more likely to have an expensive claim than most!
