Hi i bought a GTI 1.8 T 99 plate with 90k on the clock for £4500! with all the history and immaculate interior/exterior. To be honest mileage is nothing to these engines if they are looked after. Your mileage is excellent but ask your self how much someone would pay for a 6 year old car. Maybe 6500-7000 k maybe even less? im sure someone will take it off ur hands so dont loose hope
