For the last year, since buying Big red from Chris, I have been saying "I must get a set of spare keys cut". Yesterday I got in and the carpet was all screwed up in the footwell, so I removed it and laid it out flat. This was in the sun so that it would smooth out.
Drove to work (OK it's only about 1 mile). Drove to the shops (2 miles) at lunch and then back home. Went to drive back to work and noticed a shiney gleam in the drivers footwell. I bent down and picked - yes you've guessed. A set of spare keys.
Thinking back I rather vaguely recall Chris might have mentioned them the day I picked the car up.
