Gerrard on 196,000 miles.
The most serious issue I've had is when the Body Control Module had a problem that prevented high beam from working. I had to replace the BCM, with the added complication of replacing the new (second-hand) BCM's chips with my old ones, since that's where the immobilisor information is stored. I found a lad who did it for me.
Other than that, I think it's just been stuff wearing out, although that makes it sound like not much has been done to it..

In my time it's had;
New battery (no.2) @ 120k
New clutch slave cylinder (and clutch) @ 125k
New (second-hand) instrument console @ 130k
New exhuast silencer (no.2) @ 140k
New refurb'd rear calipers
New handbrake cables
New MAF, Boost Valve and MAP sensor (the latter were okay but needed to work out that the problem was the more expensive MAF)
New glow-plugs @ 140k
New radiatore (Paris ring-road traffic jam and 38C outside was too much for it)
New rear brake flexi lines
New inner CV spider
New driveshaft (the other side) @ 170k
All four wheel bearings @ 160-180k
New front dampers, springs, top-mounts @ 180k
Alternator @ 180k
Turbo boost valve intake pipe.
New (second-hand) interior light switch
Various discs and pads, tyres, oil and filters.
I also replaced a few pieces that were tatty or broken - the undertray was missing and the battery box looked like it had been removed one time and re-assembled by Herman Munster. The window switches were slightly cracked and I had to scrape off the sticky from the lights panel and controls switches... otherwise, the beast has been pretty much well-behaved.
