I just got a great deal on a Boxster, but the car comes with a few minor cosmetic issues I will or won't be fixing.
One that I'd like to fix if possible are the yellowing headlamps. It would appear that most of the wear has happened inside the headlamp, not the outside. Under the plastic lens I can see what appears to be dust and other contaminants, and the plastic turning that lovely shade of yellow.
Other than replacing the headlamps for more money than the car deserves, any suggestions?
