Glad to read that the season of good will, good injections and information given seems to be raising spirits (or wine) all round. Just to add my twopenneth worth ...
We discovered that my daughter's car had a headlight out this morning. She was chewed about this and I was thinking about stories I've heard about difficult access, sealed units and what have you. Anyway, she took some time out from work and took it to a local garage. The bulb was changed for £5. What a pleasant surprise. She is much happier now and I'm thinking that, ok, it's obviously an easy job on this car, but for that amount it's not even worth getting your hands dirty let alone trying to source the correct bulb.
