be wary of of fitting poly bushes - pro's and cons of most things, the main cons being that the vibration effects of a firmer bush = most parts down the chain to fail... but the bushes will last longer...
As mentioned, with it being a cat C it's tricky to judge and will effect the price.... so would be based on how it looks, drives and sounds, service history, when the belts were last done, when the dampers were last serviced etc... if all the above ads up then i'd say you may be able to hit £4k...
I've noticed something similar in terms of clunking, thought it maybe an issue with the clutch or gearbox, but both have been replaced in the last 2 years, so started thinking it may be gear linkage.... does it sound mechanical?
