Today's ADHD Tax: £25 for a new V5C for the car I'm part exchanging.
Got my current car 3 and a half years ago (the day the Queen died, to be exact). I can't remember for the life of me what I could have done with the V5C. No doubt just chucked it somewhere without a second thought. Spent most of this afternoon turning the house upside down to try and find out, with no luck. Gave up and paid for a new one.
