Used BMW 3 Series Convertible 2007 - 2014 review

The BMW 3 Series Convertible has a great party trick – it turns into a coupe at the flick of a switch. The folding metal roof means that you can have the wind in your hair when the weather's fair, but stay snug and warm when it's blowing a gale.

The handling is responsive with good feedback through the steering wheel, and there's plenty grip in corners. The ride is slightly firm, but shouldn't irritate.

With the roof in place you're closeted from the elements, and there's little to disturb. But even with the roof down you're effectively shielded from wind and noise.

If there is a down side, then it's passenger and luggage space. Leg room for the two rear seats is modest at best, and with the roof folded-down there's room only for a medium suitcase or a couple of holdalls.

The entire range was face-lifted in early 2010, with revised headlights, grille, front and rear bumper, mirroring the 3 Series Coupe.

The 320i model manages an official average of 42.2mpg, while the 325i does 35.8mpg, the 330i 34.9mpg and the 335i 28.5mpg. The diesels come in at an average of 53.3mpg for the 320d, 46.3mpg for the 325d and 40.9mpg for the 330d. However, owners have struggled to achieve these official figures with real-world driving.

Insurance costs are higher than rivals, with cars ranging from group 30 through to 42. Servicing costs are as you'd expect for this type of car – a bit pricey – but resale values should be strong as long as you avoid the high-powered models and don't waste money on overpriced cars loaded with options.

Petrol-powered BMW 3 Series Convertibles are cheaper on the used market, but won't hold their value as well as the diesel models. However, if the price is right they could be a great value buy.

The 170bhp 320i is decent enough, but the 215bhp 325i and 330i with 268bhp are refined and potent. The 306bhp twin-turbo 335i is rare and extremely fast.

The 174bhp 320d is the smartest choice, and will put a smile on your face while also keeping fuel bills in check. The 194bhp 325d is quicker, but noticeably less efficient. The 242bhp 330d is the better six-cylinder diesel.

All 3 Series drop-tops come with a healthy kit list as standard. The entry-level SE version gets alloys, climate control, electric seat adjustment, auto lights and wipers, parking sensors and MP3 player compatibility. M Sport adds badged items such as wheels, steering wheel, gearlever, as well as a different bodykit and cabin trim.
