The BMW 3 SERIES SALOON (2017-19) 320D 4DR SALOON 2.0 DPFR SS 190 EU6 SE AUTO8 is a premium four-door family car in the UK’s compact executive saloon class, alongside the Audi A4 and Mercedes-Benz C-Class. Its styling and roomy cabin make it an appealing, practical alternative to mainstream saloons for everyday driving. The 2.0-litre diesel and eight-speed automatic suit motorway journeys and longer commutes, delivering relaxed progress and useful fuel economy. It can serve as a family car for couples or small families, though buyers should check rear-seat and boot space against what they need from a family car.
