Space, don't worry about it. It's the sulfir thats in the gasoline. Nothing you can do about it, and nothing's wrong with your car. I brought mine to the dealer cause I was getting that very rotten egg smell out the tail pipe, and after they checked it, they said it was fine. Also, I just stared working for a SAAB dealer, and the other day I drove a 01 9-3 turbo, and it smelled like that too, when I got off the car. Believe me, there is nothing wrong with the car.
