Spitfires were the worst - The QC inspector in our Electronics Installation Agency (formerly GEEIA) had one and he had an 'unusual' start-up procedure. After he started the car, he would pop the bonnet and take a ball peen hammer from under the seat and hit the top of the alternator with it . . . . twice - That would make the Red Charge Light on the dash go out. Then close the bonnet and drive away. I told him he was the QC inspector for an Electronics Outfit, so he really should get that fixed - It's embarrassing!
He said, Are you crazy??? I drive a British Sportscar with Lucas electrics that has only one flaw . . . . and I know how to work around it - If I 'fixed' that one flaw, the damned thing would likely never run again!!
