Less than for a similar age and mileage S2000 as you might find as a private sale on pistonheads. About £5000 less than Nissan dealer advertising a very similar spec car with 14,000 more miles but 2 years younger. Sorry for being cryptic but I don't like to talk about money. One thing I can say though, IMO, is that whatever you spend (within reason) is not lost money as these cars are still very popular and as long as it's well-looked after, got full service history and desirable spec (i.e. UK may be GT).
