I bought my '07 313 roadster, 14k miles, 1 owner, SatNav + all extras, FNSH in July for £16400 - that was a pretty good price at the time! God I hope prices rise again when the weather gets nicer!
Having said that, within 60 miles of me there's only 1 313 GT Roadster with about 20k miles or less for about £14k (no sat-nav, link below), the rest are either 35-40k miles or £17.5k+.
