2003 Golf Estate

Tdi 110bhp engine. Loads of torque. I'm the third owner (8years) previous owner mechanic (10 years) who changed engine oil and filter every 6k miles. Lovely car to drive, however, now needs work. Off road for last year but started regularly until 2 months ago...my plans have changed to do timing belt and clutch and weld one outer cill to get it roadworthy again. Was a high spec car with cruise control and really good seats. Dirt in fuel put it off the road and after replacing fuel filter a few times I got fed up...so probably best to figure in dropping fuel tank as part of any work. Car had new discs and tyres for last NCT but not sure if they are salvageable now. Best car I've ever owned and I've had a fair few unfortunately.
