Erm, no not really.
I mean I have incurred the odd wear and tear items neccessary but aside from that the only real large expenses I have had to shell out for are a wheel refurb which I had done a couple of years ago (Needs doing again soon as they are now chipped) and I had one arch cut and welded at the same time.
I do need a new manifold though which will be a fair chunk of cash in the near future as I want to get a 4-2-1 s/s one and the only place I can see to get one is K-Tec which tend to overprice items!(!!!).
I seem to be one of these anomalies which have a cheap Williams to run, as even the last MOT passed with no work having to be carried out.
