After wrenching American and Japanese cars for 40 yrs I find the Boxster to have a lot of oddball one-off fasteners that are completely unnecessary. Common bolts that I access often will get the upgrade treatment to a proper metric hex or phillips fastener. This would certainly confound a dealer service tech but I am pretty certain a dealer service tech will never have the opportunity to wrench on my car.
Tamper-proof torx heads are the bane of any experienced mechanic. A set of these along with a set of star sockets is useful to remove these silly barnacles and deposit them in the metal recycling bin where they belong.
