BMW servicing is expensive but unavoidable to maintain the high residual values. This car is still very sought after in the face of its controversial replacement. Some even offer decent economy – 530d we’re looking at you.

5-Series performs fairly badly on the eco front. With an average of 238 g/km CO2 across the model line-up, its emissions are a little high for an executive estate. However, it’s worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

The range is not very frugal, averaging 30 mpg.

Reliability tends to be excellent but keep up the servicing to be on the safe side. Some owners report niggles this is not a car likely to leave you on the hard shoulder.
