BMW 3-Series - Pictures

Both offer the power of a 3.0-litre motor, but the BMW 335d’s twin turbochargers provide a distinct 62bhp and 70Nm advantage over the Merc CLK320’s powerplant

Featuring a slightly longer wheelbase, the BMW offers more space than the Mercedes. The seats in both fold down, but in the CLK, the bases also flip up

While the luggage area in the 3-Series may only be five litres smaller than the CLK’s, the overall load space is much narrower and shorter in comparison

On top of its relatively simple layout, the 335d offers everything you’d expect from a BMW – with faultless build, a great driving position and controls that operate smoothly and accurately
