You did a fantastic job on her already, it'd be rude not to finish it to the highest standard. To that end, I've been hoarding parts via eBay and the internet generally this month. So far I have bought:
All new gear linkage bushes, gear stick and knob, gaiter and other repair bits from VW Heritage:

Replacement gear level surround:

Votex centre console:

Momo Jet 3 steering wheel, 90's production so I deem it "period correct":

And finally for now, a set of refurbished genuine VW Sebring 15 inch alloy wheels:

Also currently in talks with TSR Performance and Emerald ECU about building up my 9A engine to hit around 200bhp using a full build engine with a gas flowed head and cams, ITB's and a standalone engine management system. The gearox will get a rebuild as well but with an uprated LSD fitted for good measure as well as an uprated clutch.
Still trying to source a Mk3 Golf Recaro interior at a good price, got one on my eBay watch list that I'm putting a cheeky offer in so that may be purchased soon as well, then it'll get a re-trim as well as the rest of the interior and all new carpets throughout.
Depending on how things go with the Golf R over the next few weeks, I may get round to booking it in with the restoration place to have the shell completely overhauled and refurbished, check out these guys who are about 30 minutes drive from me:
http://www.spikesvintagerestorations.com/Currently they have a Ferrari Dino, from Ferrari themselves, in for a total restoration. If Ferrari trust them, I reckon I do too! So stay tuned, things are going to get crazy very soon with this! Mk2 Golf GTI of my dreams... I reckon it's possible.
