The spreadsheet could have gone two ways... Make me not want to spend any money and just keep it as it is... Or, as I feared, (and planned) allowed me to plan my spending to get all the things I want! It's a mix of performance (standard zed performance stuff, I'm not going the FI route... I really am not!), and personalisation. The problem is I have a thing for carbon bits... And they cost lots!
Ah well, I caught zeditis before I even bought the car. I think I've had moditis from birth, it's a congenital thing, and I don't want to be cured.
