x5 01 is the first batch . some models required gearbox software upgrade. price for 01 unreg should be not more than 260k. my boss has this model .3.0 very thirsty because of it weight. ask your bro to go for 2004 model x5 3.0d wit x drive.facelift model. price around 335k. it is much faster than the
petrol . 500nm torque makes the difference. my two cents. thanks.
