Highly desirable and very pretty. Handles well even with the roof down. Lower emissions than previous MINI Convertible. Air conditioning now standard.

Options can easily add quite a lot to the final price.

MINI Convertible (2009 – 2015): At A Glance

The second generation MINI Convertible is slightly lighter and narrower than the original model yet has sightly more boot space. Another change is the pop-up rather than fixed rear roll bars, giving the Convertible a much cleaner look. At launch, the new MINI Convertible was available as a Cooper, Cooper S, and JCW but in 2010, a MINI One Convertible was added followed by the 2.0-litre Cooper SD. 

Refined and mature it may be, but all MINI Convertible models are good fun to drive, with all the grip you'd need on the road. It has a desirable image and strong residuals.

Full specifications

The electric fabric roof of the new MINI Convertible can be fully retracted or closed in just 15 seconds. In the event of a driver being caught unexpectedly by a sudden downpour, the top will go back up while driving at speeds of up to 20mph, though it's obviously best not to try this in any strength of wind.

As an alternative to taking the whole top down the front part of the roof can also be retracted to create the effect of a sunroof. This can be operated at speeds of up to 75mph.

One of the more frivolous accessories is the ‘openometer' a gauge beside the steering wheel that logs how long you have driven the car with the top down.

Apart from cute looks, its obvious advantage over something like an Mazda MX-5 is the pair of back seats. Very usefully you can fold the backrests down individually to increase bootspace from a fairly meagre 125 litres with the top down (or 170 litres with the top) to a much more useful 660 litres.

That also allows you to poke your golf clubs through. The drop down tailgate can also be used as a table when stationary and can take a load of up to 80kg. To aid loading, you can lift the rear part of the hood frame up by 35 degrees. While, for security, not only is the glovebox key lockable, the back seats are too.

What's the MINI Convertible (2009 – 2015) like to drive?

This MINI Convertible has a stiffer structure than the old model and this is important in a convertible with no roof to stop it twisting through corners.  The other benefit is that it allows the suspension to do its job properly without being compromised by a flexing body frame.

All MINI Convertible models come with start/stop, a system that shuts off the engine when the car is stopped for more than five seconds and automatically re-starts it as soon as the driver depresses the clutch. This pulls the CO2 emissions down quite a bit.

You also get standard air conditioning in all versions of the Convertible. So, though buyers spend an average of £3,000 on options for their MINI, you now get the basic essentials even in the base models.

The 120PS Cooper doesn't have a lot of grunt, of course. It would be nicer with the 150PS turbocharged version of its engine. If you want to go berserk, then your obvious choice is the 211PS MINI Cooper S John Cooper Works convertible that pulls to 62mph in 6.9 seconds.

Even with everything off, its handling is obviously more sophisticated than the previous Convertible. But it does the job in a similar way, gripping like mad and tackling corners with ease.

What compact convertibles would be a suitable replacement for a Fiat 500C?

Is there another small convertible to rival my ageing Fiat 500C? I want something that is just as compact, has a back seat to take a dog or small people and, unlike the MINI convertible, looks nice! Budget flexible.
You can get a Citroen C1 Airscape, a Peugeot 108 Airscape and a Renault Twingo with a full length canvas sunroof. All significantly cheaper new than a FIAT 500C.
