hi, i have been using an x5 since 4 years back. It is a good suv in general. So far i have only 1 problem i.e self levelling suspension inactive. It occurred after 2 years of warranty period. As my mileage is low, auto bavaria absorbed 50% repair cost. Other than that, my x5 is superb. Suggest you buy normal suspension with no self levelling. Understand x5 got various specs. Txs.
