I keep all chagnes to the car (maintenance or upgrades) in a text file in this kind of format:
5/2/03 104,586 Miles
Oil Change - Mobil 1 (Pennzoil)
RainX
6/28/03 108,659 Miles
Intake Manifold Overhaul:
Cleaned TB, UIM and LIM
Replaced head-LIM, LIM-UIM, TB, EGR, and IAC gaskets
Replaced injector O-rings
Replaced fuel pressure regulator
Replaced fuel rail to LIM seals
Cleaned MAF
Replaced Spark Plugs
7/3/03 109,086 Miles
Mounted new Yokohama ES100 summer tires on summer rims

I dont really keep maintenance receipts unless it was really pricy or out of the norm. Its nothing fancy at all, but its worked great so far.
