So my Boxster is going in to get the 'hibernation' work done in a couple of weeks and I inquired with the dealer about the clear side markers. So happens, they have them in stock and will install them while the car is there. $19 per side. Works for me.
On another note, I am not actually a doctor, my initials are 'dr' , hence the username. Although my wife is a doctor, so there is a Dr. Burton.
