I've always used the manufacturer's own site for approved used cars, in this case:

You'll get the best cars (but the highest prices) there (though they are of course subject to price negotiation).

Alternatively, I've also used Autotrader:

They have a huge selection.

See previous threads for general advice on bringing a car in (e.g. getting HPI check etc.)
