Our recommendations
Which used BMW 3 Series estate should I buy?
Engine
Chances are you’re after a diesel-engined car, as that’s how most people bought them new. If so, our favourite engine is the 320d, which has slightly more oomph than the 316d and 318d versions, and yet retains class-leading economy.
The higher powered diesel models all offer an excellent blend of performance, refinement and economy too, while the petrol engines are smoother and even more refined, but ultimately much heavier on fuel.
Specification
As for the trim levels, all 3 Series are well equipped and there isn't really a bad choice amongst them, although the firm sports suspension fitted to M Sport cars can be too jarring for some. On balance, we'd recommend Sport since it gets all the equipment form the SE model but has more supportive sports seats that are better on long journeys.
