[poopoo]

Im thinking of selling my Caterham and would like a second opinion of the value. 2004, S.V, 16,000miles, fCCsh, 6 speed gearbox, 1.8 K-series (140BHP), four pot (bigger AP brakes), leather seats, full weather gear, R3/4/500 wheels (15inch), CR500 tyres, black pack, viper blue.

Thanks. I hoping for £18,000.
