Well not quite true but I know what you mean, things like wipers, regulators and horns very seldom if ever give trouble. Starters, generators etc do require maintanence from time to time but are very easy to rebuild.
However let me save face on behalf of Lucas with this, the 'Prince of Darkness' is unfair since one thing that Lucas did exceed all others in was vehicle lighting. Lucas lights were simply second to none. As well as looking great things like the SLR700 and SFT576 fog lamps performed astonishingly. Remember also that the majority of vehicles on US roads had abysmal 6volt electrical systems with feeble candle lights that passed for illumination.
Imagine the impact the 12v British cars had on this scene after the war!
British cars have received a lot of knocks but they were affordable and could be maintained with regular tools.....it seemed like that I was always buying a special tool to work on the VW that had no use for anything else.
