you want to buy a used BAC Mono, do you? Well, you'd better have some deep pockets. You know, the kind that are made from the finest silk, and enclosed within trousers of which there are only three other pairs in existence.
Thanks simply to the fact that BAC builds so few of the things - and the Mono's status as the ultimate millionaire's plaything - it's one of those cars for which you'll have to pay more to buy a real live one than to join the back of the waiting list. Just 20 are built every year, meaning demand outstrips supply and the waiting list is around a year.
"The Mono is such an extreme machine, and it's so low volume, that there'll always be collectors and people who want to buy one just to stick in their garage," says Andy Noble. "The multi-millionaires out there, they don't care if it's £50,000 or £100,000; if they want one, they want one, and I think that will keep the price of those reasonably high because there's so few of them."
As a result, sellers can set their prices as boldly as they fancy - as evinced by the faintly ludicrous £279,950 being asked for this brand new, unused example - let's not forget, the on-the-road price of a new one is £165,125.
More reasonable is the £175,000 being asked for this 64-plate example. It might be a few years older, but with just 400 miles on the clock it's barely been used - and given how much lower the Mono's prices was back then, it'll likely be netting its owner a pretty penny if it sells for anywhere near that.
In short, if you want a Mono, the most financially effective way of getting hold of one is still - amazingly - to buy new and brave the waiting list. And if you can't be bothered to do that, then be prepared to pay over the odds.
