[pothole]

Re the clutch it's a piece of string question and much depends on how you drive the car and in what traffic conditions.

I bought my 2.5 on 76k miles with a "high and stiff" clutch which was deemed to be on its last legs by a specialist inspection.

I managed to nurse it to 117k miles before it needed changing - and it was actually the release arm bending from the added weight that eventually did it in - the clutch itself still wasn't slipping.

I rev match literally all my downshifts and don't tend to drive much in stop start traffic, which helps a lot. Nothing burns a clutch out like someone trying to drive fast but not rev matching their downshifts.

Anyway, I would budget for a clutch if the car is otherwise good and just drive it until it fails and learn to rev match if you haven't already - mainly because it's fun! If the clutch goes, no problem, you've budgeted for it. If it lasts a while, bonus!
