I was never quite sure what to think of Frank Williams as a person, I rather got the impression he wasn't the most friendly of characters, but that may well be misguided. Sad news anyway.
As for old cars, indeed whenever someone says how nostalgic they are for their old Morris/Sunbeam/whatever, I usually comment that (a) they were usually pretty awful things in reality, (b) you never want to have a crash in one.
I happened to pass a Morris 1000 today coming in the opposite direction, the stink of unburnt hydrocarbons was eyewatering (literally). A chap I worked with 30 odd years ago died in crash in a Morris 1000 on the M6, if he'd been in a modern car it's very likely he'd still be here. Be very careful in old cars (says me riding motorbikes....).
