Which used BMW 3 Series coupe should I buy?
Normally we would suggest that the 320d model, with its combination of performance and efficiency, would be the pick of the range, but two things hold us back from doing so: the known reliability issues, and a nagging feeling that a petrol engine is a better fit with a coupe.
Of the four petrols available, the 2.0-litre 320i is the level-headed choice. With 167bhp it feels fast enough, yet running costs aren't extreme. Upgrade to the smooth six-cylinder 325i or 330i, and your wallet might feel the strain. The twin-turbo 335i is rapid, but expensive to fuel, tax and insure.
