Have any of the rest of you noticed how much the MS3 stinks up a garage? I'm assuming that it is the exhaust, but I have never had a car leave this much odor. I'm not even sure how to describe the smell, but it is obvious that the car is the source.

 

I noticed this also. A friend who recently bought a Hyundai noticed a really strong smell for several months. I am a fairly new M3 owner, and I am still working through this issue. I am told it the source is a new/different type of metal they are using in the exhaust system, and it goes away after a few months. When the weather gets warmer, you may need to air out your garage.
