Well to be absolutely fair to it, I have given the next owner a damn good head start. They don't have to worry about anything like tyres, brakes, fluids, cooling system etc. What they will need to look at is having the inlet manifold off, cleaned and all the gaskets replaced in there and all of the rubber in the intake system sorted. It 'might' want an off-side rear shock too (you'ed need to do both though obviously), more likely though it's just the rear anti-roll bar drop-links causing the clonk as the handling is fine. The paint-work could be a little pricey to get sorted though, as really the boot lid could do with coming off and being resprayed entirely.
Also, the other little caveat is the rattle I get, which has been reduced quite a bit by the oil change, it absolutely drives me nuts, I hate it and this has coloured my view of the car. Maybe it's the VANOs units, maybe it's the chain on the oil-pump ...I don't know for sure and neither does anyone else. If both VANOS units want replacing though that's expensive, along with all the intake stuff that needs attention ...paint, suspension etc. I reckon someone could easily spend £2k on it to get it ...just right if it is the VANOS units.
