Great point. You have to be careful ,and try not to do what the German Engineer's did to this car, and over Engineer everything. That's why no one wants to work on these cars. It would cost you an arm and a leg to buy all the special tools that you need. I mean really, pretty much each part on the car has at least 2 different sized Torx Screws. Not to mention random 5 star ( as apposed to the standard 6 star) Torx screws thrown in there. It's made me go crazy a couple of times.
