use WagenWheels in Southampton. (www wagenwheels.co.uk).
he is an enthusiast who deals mainly with mk1s, but does mk2s also. he is superb.
he will do any job you want, from basic servicing, to track day preps, to full restorations. the bits he cant do he ships the car/parts out to people who can help.
not the cheapest, not the most expensive either but a true class act.
