The trouble with having such easy access to spare parts for the XJ6 is knowing when to stop buying them. It becomes all too easy to lose sight of the reason for doing this in the first place: to enjoy luxury motoring for minimal expenditure as long as it lasts.
Of course, I have no option but to do the work on things that mean the difference between it passing its MOT or not. However, understanding what's necessary and what isn't is important - especially to someone with a wallet-moth collection as impressive as mine.
For instance, if I press the Jag's radio-cassette player power button, sometimes I will be able to listen to the radio, but sometimes I won't. This, it seems, depends entirely on what phase the moon is in. It certainly has nothing to do with pressing the power button.
Now, I've tried oiling the aerial - which raises electronically - and gently bending it straight, but this hasn't helped. I could pay to have the wiring looked at, or get a replacement aerial, but that's expensive. So, for now, I'm enjoying the smooth hum of the Jag's straight six - accompanied by the odd clunk from the front suspension. It's a job that can wait.
