Right, long story short: I need to insure another car by June this year or else I lose 6 years of NCB. I don't actually need a car as I commute by motorbike and I can usually borrow my mum's when necessary, but it would be handy to have one occasionally for lugging stuff about or going on booze cruises. Since it'll get used very infrequently fuel economy etc. isn't much of an issue, and because of the aforementioned 6 years NCB I can insure pretty much anything with <250bhp for reasonable money.
A little article in this week's Autocar reckoned that you could get an early Vauxhall Omega estate for £500 at auction, which would suit me perfectly- something a class smaller like a Mondeo, Xantia or 406 would also be fine. So, my question is, where can I find an auction full of quasi-bangers like these? (Live in London, can travel within reason). When's a good time to buy? I don't actually need it until June, but it occurs to me that traders might have a glut of trade-ins in March, and that could tip the supply/demand equation in my favour.
All advice gratefully accepted.
