I think its working your way UP to a diesel.
Belts should be done by now, could even be on the second set.
If it seems flat and underpowered could be the MAF out, £60 and transforms the car.
Just done my clutch 79000 miles.
Good one should go well with plenty of grunt above 1200/1500 revs when the turbo kicks in,
Hope you can find a good one.
