Bigger turbo and FMIC on the 150 compared to an SMIC on the 130
150's tend to suffer from cam issues although the same cam was fitted to the 130 but I've only heard of 150 failures

What mileages are you looking at?
Just ensure the service history is up to date with cambelt changes etc. On higher mileage cars listen for any suspension creaks / groans / knocks
Apart from that they all suffer the usual MK4 faults - window clips, door modules, rear wiper motor failure etc
Think Steve_PD 150 is on approx 140K on his original clutch and turbo. His has been mapped for approx 70K I think though sadly he has suffered the camshaft failure

Apart from that he sees 600 miles to a tank
