Should be possible to get a decent 09 Focus for the top end of that budget, or an 08 at the lower end. There are a couple of Carzone at the minute, [broken link removed] or [broken link removed]
Plenty of room for haggling in the current climate if you're paying with cash.
Thanks - I see a lot of cars on Carzone with UK plates - is that ever a concern?
A friend of mine did advise me to find a dealer that will source/order a specific car for you in the UK.
