Has anyone else on here had any problems with there trophy? ive had the gas monitor warning light up several times and both sensors replaced, ive also had the cat replaced as it cracked, just got the car back from the garage again today and have been charged £140 for new spark plugs and something else not quite sure as i havent seen the bill yet! they said the car was misfiring! surely a car thats only 18months old shouldnt have this amount of problems?
