OP, at around £30-40k you could try a lightly used Evora instead? They're a much more substantial car than an Elise and if you go for an Evora S, ought to feel plenty fast enough.
They also don't seem to depreciate so have it for a few years, stick as many miles on as you like and sell it for near enough the same price again.
I used to have a VX220 as well and they're a lot more different to Elise's than some will have you believe, they're slightly longer, wider, have unique damping setups, seats are more comfortable and have torquier engines too, the NA cars won't win any drag races (think 3.0i E85 Z4 for straight line speed) but they drive sublimely and are amazingly compliant over British roads.
