Sorry I missed this thread first time around. I would have said that a friend of mine in Northern Ireland had an early 325tds from new, with a manual 'box. It managed 16 years and 270,000 miles or thereabouts before the fuel injection finally let go and it got swapped in for an E91. At that point it was still on its original clutch. I don't recall hearing about anything on that car ever going wrong or needing to be replaced apart from the usual perishables. Good steer as well, I drove it myself on several occasions.
