My MY99 car came with the rare option 635 ParkAssist (called Einparkhilfe in German). It wasn't common probably because the parking sensors themselves are really ugly. On the Boxster
'dat @ss is so pretty. These are like four warts.
After almost three years of ownership and three years of having to look at them, and also prompted by damage to my rear bumper (Another story. Nürburgring. Wet.), I decided to do a custom mod to hide them.
Don't get me wrong, the ParkAssist is great functionality even in a sports car. Our streets in Europe are much more narrow than in the US and many parking spots are simply tiny. The plan is to retain the original system, make the mod somewhat reversible, yet have a nice clean look of more modern cars.
Looking even uglier on my dirty, damaged bumper.
