Looks like a nice car, but very expensive for a 2006. Confused.com valuation says £3470 forecourt, £2770 private, £1670 p.ex. Seller's description says he's not open to offers (see bottom of the extended description) - that may change! I'd make an offer of £3000 subject to inspection.
Oh - probably irrelevant but it's not ULEZ compliant despite the tick on Autotrader
