The cheapest diesel is still pricier than the 420i petrol, but has a useful 187bhp and far brisker acceleration – 0-62mph takes a respectable 7.6sec. It’s the most efficient engine in the range, with official economy in the 60mpg range and impressively low CO2 emissions.

Sports

Munich-based BMW is most famous for its sports saloons, in particular the 3 Series and 5 Series. However, it actually builds almost every type of car imaginable: everything from two-seat convertibles to seven-seat MPVs.

The cheapest model in the BMW range is the 1 Series hatchback, which is a rival to the Audi A3, Mercedes-Benz A-Class and Volkswagen Golf. Meanwhile, at the other extreme is the i8 plug-in hybrid sports car, which costs more than £100,000.

BMW was also quick to capitalise on the rise of the SUV and now has six in its range: the X1, X2, X3, X4, X5 and X6.

All of this makes it one of the big three German prestige brands, along with Audi and Mercedes-Benz.

BMW 4 Series Convertible

The BMW 4 Series Convertible is very accomplished indeed, with keen handling, an impressively comfortable ride (when adaptive suspension is fitted), and a classy interior. It’s even surprisingly practical, so is easy to recommend over the Audi A5 and Mercedes C-Class cabriolets.

What we're looking for:<ul><li>Wind-in-the-hair excitement</li> <li>Roof that’s quick and easy to raise and lower</li> <li>Comfortable seating for four adults</li> <li>Sufficient practicality for everyday use</li> <li>Little wind buffeting</li> <li>Quietness, whether the roof is up or down</li> <li>Minimal shaking and shimmying over bumps</li></ul>

Despite the British weather, UK car buyers are among the biggest enthusiasts for wind-in-your-hair motoring, so convertibles have always been surprisingly popular here. It’s best to be able to react to the fickle climate, though, so we’re after a roof that opens (and closes) slickly and quickly and good top-down cruising refinement.

There are precious few bespoke drop-tops these days, so your choice of models is generally limited to soft-top&nbsp;versions of existing models. Mini will sell you a drop-top version of its style-focused hatchback, if you’re after a bit of flair. The Audi A5&nbsp;Cabriolet, meanwhile, brings all of the benefits of the regular A5&nbsp;– refined engines and a beautifully finished interior. Alternatively, the much more expensive Mercedes-Benz S-Class Cabriolet is one of the most luxurious convertibles on sale.
