BMW 5 Series SE Business Edition.
What to Check Before Buying.

The BMW 5 Series SE Business Edition targets company car drivers and business professionals seeking a premium executive saloon with strong tax efficiency and corporate appeal. This trim typically combines the 2.0-litre diesel engine with professional-focused features including enhanced connectivity, navigation, and comfort specifications that make long motorway journeys more bearable. The diesel variants offer excellent fuel economy, often achieving 50-60 mpg, though the complexity of BMW's emissions systems means potential buyers should verify the DPF (diesel particulate filter) has been properly maintained with regular motorway use rather than short urban trips. When inspecting a used SE Business Edition, check the full BMW service history is present, as missed services can trigger expensive repairs on the turbocharger and emissions equipment. Examine the professional navigation system and digital displays function correctly, as screen replacements prove costly. Verify the automatic gearbox shifts smoothly without hesitation, and inspect interior leather for wear on the driver's seat bolster, which is common on higher mileage examples. A Folt vehicle check reveals service history gaps and outstanding finance before viewing.
