I have a 2000 x plate with 85k miles, the steering wheel, pedal rubbers and gear gaiter are all in great condition. The trim material in the mk4 is generally good so I would be a bit suspicious at anything looking worn at those mileages....
Phone the garages that did the servicing, ask them what the milage was at the last service. If you're lucky its had a full vw service so all the records will be computerised and they will be able to tell you everything thats been done and more importantly at what mileage.
