... you hear something rattle off the floorpan at 50 mph which sounds decidedly 'bolt like'.
If you've never been there, then thank yourself lucky, if you have - then you know how I feel!
This is the second time I've had the unfortunate luck of a bolt firing loose from the engine bay and bouncing between the floorpan and ground on its way out.
I pulled over immediately, had a scoot about, nothing looked out of the ordinary, went to pull away and you could feel the engine kick HARD. So I the 100 metres left to the house (as I couldn't bare calling AA to be flat-bedded 100 metres!) and had a better look ...
... spot what's missing
