Im on 141k
Had to replace gearbox twice, the original one and the diff bearings went on it and replaced with a second hand one which blew a hole out the side of the diff from the bellhousing side

and replaced with another secondhand one, touch wood its going great. Also replaced the clutch and conversion solid flywheel when the box was off. Also had to replace a drivers sdie drive shaft as whe i went to a test drive after the gearbox was changed the first time it snapped for some strange reason.
I have also replaced brake discs all round and handbrake cables,new exhaust centre section (This sort of stuff is expected) taken the calipers apart and greaed them up, drivers rear is know to be a sticky one.
Replaced the thermostat and due to being a tool and not covering my alternator i had to replace the alternator and while i was at it changed the belt.
But apart from that i haven had anything else. The gearbox and clutch and flywheel was the most expensive thing i had to change but i also only bought my car with 116 on the clock and very limited previous owner history.
But in all honesty i love the car to bits, easy on diesel returning easily 60mpg, seen 68mpg on the motorway one day tippin along at 60mph..Everything depends on the previous owner, if they were hard on the car you can expect to have to spend a few quid on it.
