Oh God!! We can't even agree on simple things, wait til he mentions brakes!!!
Having driv my Traveller through the winter, local trips/ short journeys, with the headlights and wipers on, I can assure you the dynamo is definitely NOT up to this kind of work! Mid-January was the point at which I gave in and fitted an alternator, in the snow. Listen not to all the "if it breaks down..." comments- alternators have been proven for some fair few years now! And currently available NEW for about £40!
Same sentiment re electronic ignition- highly unlikely to fail, unlike the rubbish contact breakers on the market nowadays. I found it embarrassing fiddling at the roadside with temperamental sparks while the passing drivers were smirking at my old crock! (There is a method of fitting the late Metro/ Mini electronic ignition distributor which is what I did, simplish and relatively cheap if you can track down a breakers yard!)
I live in the south and use my car as a serious daily driver so don't see the objection to simple reliability mods, however, as you get further North, you may find peoples attitudes to things changes
Now, about the brakes.....
