I have all my 300D receipts, but I've never organized them. I think I've replaced most of the moving parts at least once over the last 300k+ miles. From what I remember, the big pieces include:

Used engine
New transmission
Half shafts
Front suspension
Several AC systems (about 4)
Several alternators (about 3)
Two or three blower motors
Two climate controls
Auxiliary water pump
Radiator
Oil cooler and hoses
Two or three fan clutches
A few water pumps
Glow plug relay
Starter
Master cylinder
Front calipers
Cruise control (everything)
More brakes, rotors, tires than I remember

I still haven't done the rear suspension yet and the car is about due for paint.
