i bought a 2002 x trail 2 litre petrol with only 60,000 miles, i would advise any one thinking of a petrol to steer well clear go for the diesel. mine was very under powered and kept having the engine management light coming on. it was apparently a sensor on the exhaust system and nissan said it was fine, but then towing my 1300kg caravan up the m 1 the engine blew luckily it was still under warrenty so it didnt cost me. straight after i traded it in for the diesel which is a great vehicle
