Sad to say I have a few,
still have the gear lever and extension from my first car an original Vauxhall viva, managed to fit it to a mk6 escort a few years ago and its now waiting to get used again (had to wait 25 years last time) also have the exhaust tail trim from my first kit car (30 years and still waiting) and then there's my twin 40 weber carbs from my first ford a 1600 mk2 escort which after 20 years were reconditioned that was 10 years ago and they still have not found a new engine to be fitted to.

Lots of cars have been and gone but its only these old parts from my firsts that I kept and they will be used again its just a matter of when.

actually I still have a badge from a mgb gt. I bought it because it was missing and it never got fitted, wonder what else I have lying around?
