I'd say things here are a little bit stricter than they are down in CA.
Definitely a hell of a lot stricter than UT and CO.
Vehicle registrations here contain almost every vehicle spec you can imagine. Any deviation from those specs require an exemption from the TüV (Safety and Emissions) which costs money.
For example, you can't just throw on a different set of rims unless they meet the same specs as your OEM rims.
So basically, unless you're willing to spend beau coup money, you're probably not going to be a doing a lot of modifying/tuning.
Guess the Germans figure since their cars are so nice from the factory there's no need to mess about with them.
