Well - it had to happen at some point, and fortunately it was whilst staying with friends. The Micra had a hissy fit and decided not to start. Incredibly the AA arrived within 20 minutes - that never seems to happen when you're in a real hurry or stuck in the middle of nowhere! Anyway, the lovely Phil did a wonderful job and got the car going again - a spark plug problem apparently. Note to self: must learn to make do and mend car just like hat.
