If you would be willing to build a bike up from scratch, there's a very interesting and rare frameset for sale in Lincoln, currently on eBay and not attracting much attention (although that may change with last second sniping). It seems to be about your size, although it's really a cross bike, rather than a road bike. You could definitely use this as a road bike, and as an offroad bike (for cyclocross-type riding), but it's not what is typically thought of as a "road bike."

That said, it's an awesome bike, and IF it were in my size, I would be placing the winning bid on it.

Because you're in Lincoln, you can "afford" (hypothetically, assuming money is not an issue) to bid higher than others, because you won't have to figure in shipping costs.

Here's the frameset (I'm almost certain it's a 1990): Bianchi Equinox



And here's what that bike looks like built up (another bikeforums member has the same bike):
