Used BMW 4 Series for sale

Stability control, multiple airbags and ISOFIX mounts are standard. Later models layer on lane departure warning, automatic emergency braking and adaptive cruise. Strong brakes and solid crash-test scores give it real peace-of-mind appeal.

Take your pick: early cars range from efficient four-cylinder diesels like the 420d to silky six-cylinder petrols like the 440i. The latest generation adds mild-hybrid tech for cleaner power. Most are autos, but a few manuals are still out there.

iDrive infotainment is the intuitive and reliable backbone, with satnav, DAB, Bluetooth and USB as standard. Higher trims step you up with bigger screens, wireless charging and premium Harman Kardon audio. Even early models feel modern inside.

Diesel 418d and 420d versions can return close to 60mpg, while six-cylinder diesels balance punch with mid-40s efficiency. Petrols average 40 to 45mpg. Real-world figures shift with driving style, but the blend of performance and economy is a strong suit.

Service history is non-negotiable, as BMW engines need careful oil changes. Look out for electrical glitches, worn tyres or suspension on big-wheel cars, and check that the infotainment runs smoothly. Convertible buyers should test the roof mechanism, too. For extra peace of mind, consider The AA Vehicle Inspection, especially if you're buying privately.

Mechanically, yes. The six-cylinder engines in particular are proven workhorses. The most common grievances are electrical sensors, which are usually cheap to fix. Keep on top of servicing, and the 4 Series will reward you with dependable, enjoyable ownership.
