Belts should be done every 4 years or 48 K and with the torque you get with a tuned one its worth doing, sooner rather than later.
My one had a new clutch at 75k, cost about £330.
The MAF sensor goes and they wont pull and feel flat, the MAF sensor is £130 ish, I think.
Normal brake problems, sticky sliders/calipers.
Tyres at the front can wear on the inside edges, so worth checking all four and get down and look at inside edges. From outside the car tyres can look perfect.
Dont have many HGF but just check the colour of the coolant, go for a run should be on half way on temp scale. It can take 5 mins or so to get up to temp.
Just remembered we have a guide as well.
