Make those headlights new again Clive. Yours need cleaning, as they all do over time. Dust gets in everywhere unfortunately.
Remove the headlight clips with flat tipped screwdriver (8 clips in all I think - 4 on top, 4 on bottom) then strip down lights using a steel butter knife by carefully prying the glass lens away from the housing seal, a little bit at a time working your way around the lens. The seal can be reused.
Use a dust blower (rocket air dust blower or similar) to remove excess dust from the reflectors, then a very damp (near wet) sponge or cloth to carefully wipe remaining dust from reflectors. Don’t rub as it is delicate, and DON'T use any chemicals or polishing creams, just clean water. The chrome can come off if you’re not careful. Lightly polish the chrome with a lens cleaning cloth (the one you clean your favourite pair of sunnies with), then reassemble with care. The lighting will be vastly improved and car will look even better.
Finally, give your tailpipe a spray with VHT flame proof header paint (Flat Black), and congrats on getting yourself such a nice car.
