So when I type it out it's really not all that bad. If you forget the rims and tires, suspension, turbo inlet pipe and diverter valve, it really has been low cost.
So things I have had to replace so far
Brake pads and rotors, rear
Coolant flange
CTS
Heater hose supply line
Maf
Spark plugs
Coil packs
Air filter
Turbo inlet pipe
DV
Valve cover gasket
Coolant flush and fill
Passenger front and rear window regulators and motor
Avus 17" wheels and 225/45/17 extreme contact tires
RS style grill
Lower door mouldings passenger front and rear doors.
