My headlights are getting "fogged over" on the inside. Someone told me that the European headlights were glass and not plastic. Does anyone know if this is true? If so how would I go about getting a set. I know it would be very expensive.

No - glass lenses were a mod back in the day like e36 and e46 i think.
X3 is plastic.

Looks like around 260 USD if you buying from USA person.

Try using the lens polishing kits. They are very effective. Used on my Daughters honda Pilot and my Subaru Outback. They look brand new.

Google it and you will see how it done. Also, many Detail shops offer this service. You car will look much better. Im guessing around 75.00

I confirm that the headlights on my french X3 F25 are made with plastic not glasses
