Too late!
I've changed it to a 4-lamp grill (all crystal lights) with a 'GTi' badge on the front and it looks amazing, especially with the uprated headlight bulbs. I've also removed the eyebrow spoiler - which I might attach again when I'm feeling a bit brave to drill holes in the grille!
As for the convertible...
My girlf and I are insured on each others cars and, obvioulsy, she drives the convertible more...and I drive the Mk2. When I need to do a bit of posing, I whack on the TopGun shades, put the roof down and mince about town
My Mk2 had its MOT over the weekend, they (VW dealership of course) also fitted a
weighted gearshift from a Mk3 Golf and took it upon themselves to tune the car...oh...my...god did it make a difference! Maybe I'm a bit closer to the 150bhp now? Soon I'll find out because I'm got a rolling road day this Saturday.
