How much will the price of a BMW 520d drop to in 2015?

Hi Fionn,

You see, if we could answer that then we would have cracked the deep and dark mysteries of car depreciation and possibly time travel. In which case this would be written from the deck of our yacht, moored in the Caribbean. But it's not, so the short answer is we don't know. Fifty per cent depreciation over the first three years is the normal rule of thumb for most cars, and a 5 Series diesel would drop in value a little slower than that. So a five-year old one would probably be worth just under half of what it cost when new, assuming it's in perfect condition and has a full service history.

Hope that's of some assistance!
