Advice for buyers
What should I look for in a used BMW 5 Series saloon?
The thing that's most likely to go wrong is the cooling system. It's responsible for no less than a quarter of all visits to the workshop, so pay close attention to the engine temperature when you're test driving and get the work done if it's dodgy.
Give the air-con a run for its money, too, to see that it can still blow hot and cold on demand.
