couple of things that haven't been said but I think are very important:

1: timing belt changes every 100000kms
2: Water pump changes every 100000kms
3: Oil Pump changes - not sure about the replacement frequency but maybe 200K anyway
4: 10000km coolant changes

those 4 things apart from oil changes and fuel filter changes will ensure your car is running tip top.

My EW5 when pulled apart showed almost no use on the piston bores, cyl head was perfect as well. When I took it for a shave the guy asked how many kms the cars done (240000) - he said its impossible, it looks like new! only reason I did a rebuild was because the oil pump failed at 240000kms.
