What should I be paying?
Even standard SE spec has all you’d need, though some of the chassis options are tempting. Light weight and good aero help keep the CO2 figures down for low tax. On that subject, soon after launch there will be a 530e plug-in hybrid giving 44g/km rated CO2. More realistically economical is the forthcoming 520d EfficientDynamics, with an impressive 102g/km and 190bhp combo. So you’ll pay little tax. Most of the 5 Series range’s insurance and service costs are ruthlessly benchmarked too, so your employer can’t complain either.
