I met a young couple once who managed to get a bank loan to install central heating in their house. Once the money was in their account they decided central heating was boring, so instead they blew it on a joyride each in a Spitfire!!
The point of this little story is that, even if you can find someone offering them (and two-seater Spitfires are really rare) it's going to cost a lot more than the same in a Tiger Moth.
