Our new horseless carriage is really a great hobby.  Today H undertook the challenge of installing a snazzy new car stereo, complete with windscreen antenna, IPod dock, CD and SD card slot.  The original radio was not included, which was probably a good thing since we'd have settled for that one, but negotiating the hydra tangle of coloured cables and wires, H made it work.  The job looked intimidating and I imagine that only members of the bomb-squad (or the mod-squad) would have the patience or endurance to even try replacing a radio without professional help.  A few weeks ago, I changed the battery (which was not meant to be replaced outside of the factory) and felt SWAT-like pressure in doing so.  I am just enamoured with this old car, its unelaborated dash board with three essential dials, and accessible, no-nonsense innards.  I am sure\that we can keep it running and fancy for a very long time.
