Royal blue & bright blue metalic are pretty rare colours (just try finding panels for one!) Compared to oak green which is relativly comon in comparison.
You'll be hard pressed to find a standard 'top spec' MK2 in the UK, we are mostly too tight to order all the extras :grin: Most of the bits can be found on ebay/in the classifieds and added yourself though, your best bet is to get one with good bodywork and work from there

A full specced MK2 would include these standard extras:
Top tint rear lights (standard on most 16v models and run out 8vs)
Roof aerial (Bee sting, again standard on most 16v models and run out 8vs)
Central locking
Green tint glass (or even chromlux if buying a Golf limited or Rallye/G60)
Power Steering (the 16v had a slightly more 'sporty' rack apparently)
Electric windows
Electric heated mirrors
Fischer 6 Cd holder for the std centre console
Leather steering wheel
Headlight washers (v. rare)
Votex centre console (v. v. rare)
Electric heated Recaros (v. v. v. rare)
Air conditioning (v. v. v. v. rare)
Electric adjust headlight range (v. v. v. v. v. rare)
Have I forgotten anything?

You can also get pop out rear quarters for the 3 door models as an aftermarket accessory, but be prepared to spend a fortune on a set, the green tint ones are especially hard to find!
