Any advice on buying a used BMW 5 Series?

Hi Susan,

You should be fine - that's the current model and it hasn't thrown up any major reliability issues. BMW also seems to have fixed a long-standing concern over the reliability of the timing belts on its 2.0-litre diesel engine, as well as some weaknesses around the turbos. That said, unless the car has a pristine and fully stamped service history (preferably from a BMW main dealer) then avoid it - they're complicated things and any skimping on maintenance by a former owner will come back to haunt you.
