Reminds me about a story I heard years ago from a mechanic who used to work at a Rolls Royce dealer. Just after WW2 finished a Major wanted to go to France to view some battlefields he had been in, so along he went with his wife in Rolls Royce car, just a few days into his holiday in France the Rolls broke down. He contacted RR in England and they sent two mechanics to him about two days later. They repaired the car in a few hours. The Major continued his tour of France, and back in England a few weeks later thought to himself I haven't had the bill yet from RR, so he contacted them and explained the problem. He was told he must be mistaken, as RR cars don't break down.
