I've got every receipt for everything I have bought/had done to the car since I bought it (2 years ago). When I say everything, I mean everything, bulbs, coolant, filters, speakers, paint, belts, tyres and the thing that the break down man gives you to sign. Even got every receipt for every tank of fuel I have put in - all from the same place. Sad I know. Also got a spreadsheet going of how much I've spent and the date I bought each item
Got every tax disc from when it was new in a frame - very sad.
