BMW 4-Series Coupe (2013 - 2020) 420d M Sport 2d Auto Owner Review

EGR Valve failed within the first 18 months leading to an awkward breakdown, otherwise it’s been faultless. Engine is a little noisy outside the car, but excellent responsiveness, performance and economic too. Automatic gearbox is fantastically smooth. Ample space up front, coupe styling means the rear isn’t great for fully grown adults, but that doesn’t bother me.
