What's a Haynes Worth?

[skov]

Hello All,
Just wondered if anyone had any idea what a completed/IVA'd/registered Haynes Roadster might be worth?
Have any been up for sale recently?

Reason I ask (and you're not going to like this!) is that I'm considering selling mine.
I don't really have the time or inclination to drive it at the moment, and it's just sitting in the garage taking up a load of space

Cheers,
John
