MINI Cooper Convertible Review

The MINI Cooper Convertible has followed a very consistent recipe for years. It's a small two-door with four seats, a fabric roof that folds away quickly and a character that majors on style and fun rather than outright practicality. MINI has never really tried to turn it into anything more serious than that, and it's better for it.

That formula matters even more now because there's almost nothing else quite like it left. Once, buyers had plenty of small and relatively affordable convertibles to choose from. Now the MINI Cooper Convertible is one of the last cars of its kind, and that gives it an appeal that goes beyond brand loyalty or nostalgic design.

The latest model doesn't try to reinvent the idea. Instead, it refines it. The exterior is cleaner and slightly more modern, the interior is a much bigger visual step forward and the overall feel is more grown-up without losing the sense of cheeky charm buyers expect.

It also helps that, roof up, the MINI Cooper Convertible is more convincing than many convertibles used to be. There's less of the flimsiness and compromise that once came with open-top motoring at this end of the market. It still feels like a MINI first and a convertible second, which is exactly how it should.

Underneath, it's more closely related to the outgoing petrol MINI than the all-new electric one, which explains why the dimensions and packaging feel familiar. That's no bad thing in dynamic terms, because the old car was already good to drive, but it does mean the Convertible is still quite tight for passenger and luggage space.

There's also a clearer split in the range than the regular hatchback now. The Convertible remains petrol-only, with no electric version in the current line-up. That keeps the proposition simple. You choose between Cooper C, Cooper S and John Cooper Works, then decide whether Classic, Exclusive or Sport trim best suits your taste where available.

The result is a car with a very clear identity. The MINI Cooper Convertible is not bought because it's the roomiest or most rational small car. It's bought because it feels special, and because there are almost no other cars at this price that can offer the same mix of open-top fun, cheeky styling and premium ambience.

For most buyers, the MINI Cooper Convertible C in Exclusive trim is likely to be the sweet spot. The 163PS 1.5-litre three-cylinder engine should be brisk enough for the sort of use this car is best at, and it avoids the sizeable jump in price to the Cooper S.

That's important because the Convertible is already an emotional purchase. Keeping a lid on the price wherever possible makes a lot of sense, especially when the Cooper C still gets the same basic roof-down experience, the same eye-catching interior and the same core charm.

The Cooper S is the one to go for if you want the strongest all-round performance. Its 2.0-litre engine suits the MINI well, giving it more effortless punch and making it feel quicker and more grown-up on faster roads. It's also the version most likely to satisfy buyers who want the MINI Cooper Convertible to feel properly brisk rather than just lively.

John Cooper Works versions sit on top of the range and add more pace again, but they also push the MINI deeper into indulgent territory. That makes them more of a niche choice than the core recommendation.

In trim terms, Classic already gives you the main MINI experience, but Exclusive feels like the most natural fit for the Convertible. It plays into the premium side of the car’s character without making it look overly aggressive. Sport is the extrovert choice and suits the S well, but it's not essential to enjoying what makes the Convertible good.

The current MINI Cooper Convertible range starts at £28,715 for the Cooper C Classic. Exclusive and Sport versions climb from there, the Cooper S starts at £31,715 and the range reaches £35,215 for the Cooper S Sport before you start adding option packs.

That means the MINI Cooper Convertible is not a cheap way into small-car motoring, but it also is not trying to be. Buyers are paying for a niche product with a premium badge, a distinctive design and a type of open-top experience very few rivals now offer.

At the lower end of the range, it actually looks fairly reasonable in context. The bigger issue is how quickly the numbers rise once you start moving up the engine and trim ladder or adding MINI’s option packs.

That's where restraint matters. A sensibly specified Cooper C or Cooper S still makes a decent case. A heavily optioned car can become far harder to justify on pure value.

The Fiat 500C is the nearest thing to a small convertible rival left at this end of the market, though it offers a different kind of open-air experience. Its roof is closer to a full-length fabric sunroof than a full convertible set-up, and it doesn't feel as substantial or as engaging to drive as the MINI.

The Mazda MX-5 is the other obvious alternative if your priority is roof-down fun above all else. It's the sharper sports car and the more focused driver’s choice, but it also asks for a much bigger practicality sacrifice because it's strictly a two-seater.

Beyond that, most alternatives are not really direct alternatives. If you're prepared to sacrifice the folding roof, then an Audi A1 or Volkswagen Polo are easier to justify as everyday small cars. But neither delivers what the MINI Cooper Convertible does when the sun comes out.

That's really the point. Buyers are not choosing this MINI because it wins the normal small-car comparison test. They are choosing it because hardly anything else offers the same open-air appeal for the money.

The front of the cabin is where the MINI Cooper Convertible makes the strongest case for itself as an everyday car. The driving position is spot on, with plenty of seat and steering adjustment, and the seats themselves are comfortable and supportive.

There's also a surprising sense of width and openness from the front, helped by the upright windscreen and the simple, horizontal dashboard layout. Even with the roof up, it doesn't feel cramped in the way some small convertibles can.

Storage is acceptable rather than generous. There's room for the daily essentials, but this remains a compact two-door car and it never disguises that fact.

The rear seats are really where the MINI Cooper Convertible’s practical limitations show. On paper it's a four-seater, and there are indeed two usable rear chairs, but the space back there's tight and access is awkward. Adults will tolerate short journeys, though it's clearly not a place they will want to spend long distances.

That means the rear seats are better thought of as occasional passenger space or somewhere to throw coats and bags. If you regularly need to carry adults in comfort, this is not the MINI for you.

The boot is similarly compromised. With the roof up, the MINI Cooper Convertible offers 215 litres, which is already small. Lower the roof and that drops to 160 litres, so packing for a weekend away requires a bit of thought. The narrow opening also limits what you can get in, even before you worry about the quoted capacity.

In fairness, none of this should come as a surprise. This is still more practical than a strict two-seat roadster, but it's very much a style-first drop-top rather than a do-everything small hatch.

The MINI Cooper Convertible measures 3,879mm long, 1,744mm wide & 1,431mm high.

That compact footprint is a big part of the MINI’s appeal. It helps make the car feel nimble and easy to manoeuvre, and it means the Convertible still works well in town despite its lifestyle focus.

The round OLED touchscreen is the centrepiece of the new MINI interior and it gives the Convertible a huge amount of showroom appeal. It looks fantastic, the graphics are sharp and the whole set-up feels much more integrated than the previous generation’s attempt to combine a rectangular screen with a round housing.

The system is also impressively responsive. It feels quick enough, crisp enough and modern enough to suit the MINI’s premium aspirations.

The frustration is that MINI has packed a lot into it. The screen can look cluttered, some functions are not placed where you naturally expect them to be and there's a learning curve that feels steeper than it should in a small car.

Apple CarPlay and Android Auto help, and some drivers may find phone mirroring simpler than MINI’s own set-up for many tasks. The optional head-up display is also particularly useful here because it gives you a cleaner way to see key information without depending so heavily on the central screen.

Material quality is one of the MINI Cooper Convertible’s strongest points. The knitted fabrics on the dash and doors, the coloured trim accents and the general attention to detail all help it feel far more special than most small cars.

It's not just about looking expensive either. The cabin has a chunky, solid feel to it that makes the MINI seem built to last. That was a strength of the old car and it remains true here.

Exclusive trim best shows off this side of the Convertible, with smarter upholstery and a more elegant colour and trim treatment. Sport goes in a darker, more aggressive direction. Both work well, but they change the tone of the car quite noticeably.

The MINI Cooper Convertible range starts with the Cooper C, moves up to the Cooper S and tops out with the John Cooper Works.

The Cooper C is likely to be the value choice. Its three-cylinder engine should be strong enough for most buyers, and it keeps the MINI’s breezy, playful feel without asking you to pay a heavy premium.

The Cooper S is probably the most convincing all-round engine for this car. The extra shove suits the Convertible’s more grown-up side, gives it useful punch on faster roads and makes it feel more effortless when fully loaded or overtaking.

John Cooper Works versions add another layer of pace, but at that point the MINI Cooper Convertible starts to feel more like a niche indulgence than the obvious sweet spot.

Every version uses a seven-speed dual-clutch automatic gearbox. It shifts smoothly enough and suits the car’s broad character, but the lack of meaningful manual control in the regular range still feels like a missed opportunity in a car that otherwise encourages driver involvement.

What makes the MINI Cooper Convertible appealing is that it still feels like a MINI first and a convertible second. The steering is quick, the front end turns in eagerly and the car feels keen to change direction in a way most small cars do not.

There's still a nice sense of agility here, and the chassis has enough balance to feel playful without becoming hard work. It's not a pure sports car, but it's one of the most entertaining small front-wheel-drive cars you can buy.

The suspension is firm, as you would expect. The Convertible feels taut over bumps and rougher town surfaces in a way that a Volkswagen Polo doesn't. But it's also well damped, and that means it stays on the right side of being sporty rather than merely uncomfortable.

The Cooper S is especially enjoyable because it has the performance to match the chassis. It feels brisk, eager and just a little more complete than the entry-level car without losing the ease of use that makes the Convertible work day to day.

Roof up, refinement is better than you might expect. The MINI does a good job of keeping wind and road noise under control, and it never feels flimsy or loose in the way some convertibles once did.

Roof down, the experience is still surprisingly civilised. You obviously get more wind in the cabin, but there's not much of the structural shake that can afflict softer open-top cars. That means the MINI Cooper Convertible feels like a mature car with a party piece, rather than a compromised novelty.

Unlike the hard-top MINI Cooper, the Convertible doesn't yet have a separate current rating from independent safety organisation Euro NCAP.

That means it's better to judge it by its standard safety kit rather than assume the hatchback’s score applies directly. Every MINI Cooper Convertible gets autonomous emergency braking, lane departure warning, traffic-sign recognition, stability control and a reversing camera, while higher trims and packs add more advanced assistance features.

That's a useful safety baseline, but it would still be good to see a current independent crash-test result for the Convertible itself.

The Cooper C manages up to 43.5mpg, while the Cooper S is only slightly behind at up to 43.5mpg depending on specification. Even the John Cooper Works still returns up to 40.9mpg.

Those are respectable figures for a small petrol convertible with this much performance and character. In real-world use, you should expect lower numbers than that, but the MINI Cooper Convertible still looks reasonably efficient for what it is.

MINI covers the Convertible with a three-year, unlimited-mileage warranty.

MINI also offers Service Inclusive plans, which can help make routine maintenance costs easier to predict if you buy new. That makes ownership costs a bit easier to plan and suits a car like this well.

Insurance groups for the current MINI Cooper Convertible range run from 23 to 28 (of 50) for the mainstream Cooper C and Cooper S line-up.

That puts it above many ordinary superminis, which is no real surprise given the MINI’s price, performance and niche body style. It's worth checking quotes carefully, especially if you're a younger buyer.

The standard Vehicle Excise Duty (VED or road tax) rate from the second year onwards is £200 a year.

The MINI Cooper Convertible doesn't incur the Expensive Car Supplement, because current list prices stay below the £40,000 threshold. That means there's no extra annual charge from years two to six.
