Which used BMW 5 Series saloon should I buy?
SE and Sport versions of the BMW 5 Series offer plenty of toys, and do without the larger wheels that make the M Sport versions ride harshly, so they’re the ones we’d go for. A 520d offers a great blend of performance and fuel efficiency, although if you don’t do that many miles every year, you might find it’s cheaper in the long run to buy a petrol-powered 520i.
As mentioned in our advice for buyers, there are question marks over the reliability of the earlier diesel engine, so if you are going for a 518d or 520d and can afford to buy one with the later twin-turbo engine, introduced in late 2014, it’s worth doing so. You can tell the difference because the later engine has ‘TwinPower Turbo’ written on its top.
If you’d rather have something with a little more power, the 530d is also a fine choice, but for those in search of the ultimate in saloon performance, the M5 is the one to have.
