ferman dealers seem very OK with mods, as far as I can tell.
Every time i take mine (MS6, the fatter version of you guys

) for oil or for warranty work they haven't even made a peep about the intake or the three sets of HIDs or anything else.
I've even talked to an MS3 owner that's noticed the same thing, he has his car modded the hell out, and he was there getting something fixed under warranty i think. something like that.
I love the dolphin-black color of one of those MS3's up a few posts at that meet. Very sexy.
