brought my 2002 xr6 3 years ago with 112,000 on it, now at 161,000. replaced the following
-clutch (very heavy, though this was the problem)
-clutch cable (better, but still not great)
-radiator (bottom tank slight leak)
-spark plugs, leads and coil pack (had a miss under load)
-inlet manifold gasket (as above)
-speedo drive o ring (very very slight drip)
-drivers side wheel bearing (noisy)
-auto belt tensioner (noisy pulley)
-firewall cracked right around the clutch cable. got the car back a few days ago, going much better and the clutch perfect now.
im sure theres more but that's all I can think of.
Then of course normal maintenance things like oil changes, coolant flush, battery etc, but all cars need that
