Just thought I'd add a recommendation for Tony at Automotive Solutions. Just bought my second Mk2 GTi (Owned the first years ago).
Automotive solutions were polite,helpfull and knowledgeable. Pricing was good. They also do track days in their own Golf!
Note, I'm not affiliated with them in anyway, just a happy customer.
Cheers, Rob.
