Hi Michael,
Sorry, I didn't bring my car over from Europe. My 16V is a U.S. model with catalytic converter. It does have the self-leveling hydraulic suspension(SLS), but one of the shocks was bad, so I replaced the entire system with conventional Bilstein Heavy Duty shocks and Eibach springs. It can be very expensive to keep the SLS because parts cost so much. You might want to try posting this on the 190 Forum, as I know there are a few people with Euro 16V's that can tell you some of the problems they have with their cars in regards to registering it and passing smog checks. Here is the link
