Thanks for the replies fellas. I know quotes are based on stats, but to one who knows little about the details it's all very unclear. Til recently, we had an 'affordable' quote (about £1400 - yes, that's quite good these days for a new driver) for the car we were looking to buy and now, having found the car, that quote had disappeared and the lowest was about £3.5k, more than double.
I'm also on a car forum where I've been asking people to help me figure out what's going on - the same car, same use and storage registered at a tiny fraction of the insurance cost in one part of the country compared to the quote we got for the same car where we are. The only variable seems to be geography, and there was I thinking we lived in a low-crime area.
I think I've tried all the options with no significant shift in price - the only option now is calling the classic car specialists (it's 30 years old). If prices were likely to drop with a recession, he could go ahead and get provisional licence cover (cheap) and switch once he has his licence (which could be a long, long way off with the present circumstances) and then take out full licence cover. But nothing seems so predictable these days! :?
