Thought you were a mechanic and knew what was happening under a bonnet CW?
In all fairness modern vehicles don't need anything like the attention of the old stuff. Remember my first car and always having to be under the bonnet adjusting points, carb, cleaning plugs etc. Trouble is they get to an age were a sensor or electronic component lets go and that's it, throw it away.
Can't see much modern stuff being persevered with in 60 years time. Few people will be interested in re-making the parts for them. Look at the old stuff, simple and rugged, nothing complicated it could be made/re-made to go on forever.
