mines now 127,000, in its life its NEEDED a new alternator, n/s driveshaft,icv and exhaust
Iv replaced out of choice:
uprated brakes
new renault shocks with prolines
new front wishbones
the car is still on its original box and clutch, and even with just a stainless exhaust kicked out 141bhp@ the wheels
So id say no problems with age if they looked after chap
and dont worry about the head work, any car could have had engine work in the past and the owner could be dis honest, he has told you what wentr wrong and its been fixed properly so that wouldn't put me off at all
