Best Convertible Cars 2026: The UK's Most Popular Cabriolets

At Cayman Autos, we speak to convertible owners all day, every day. Their cars pass through our workshop in a constant stream of soft-tops and cabriolets, which means we see the market from an angle no dealership or review site does: we know which roofs hold up, which ones give trouble, and what they cost to put right.

And unlike a dealer, we have no interest in selling you any particular make or model.

So with the warmer months well underway and long evenings still ahead, it is peak convertible season across the UK. Here is our answer to the question we hear more than any other: what is the best convertible car to buy in 2026?

The quick answer

If you want one recommendation, buy a Mazda MX-5. It is the most fun for the money, the most reliable of the group, and the car that almost every UK expert still rates as the best convertible on sale. If you need four seats, look at the BMW 4 Series Convertible or Mercedes CLE Cabriolet. If you want to go electric, the MG Cyberster leads a small but growing field.

The 6 Most Popular Convertible Cars of 2026

Prices are approximate 2026 starting figures and vary by trim and options.

Mazda MX - 5

Best for: Fun driving with a reasonable price tag

Starting at around £28,600, the latest Mazda MX-5 remains the benchmark. It is one of the few reasonably priced convertible sports cars left on the market, and it comes into its own on a twisting country road, where its light weight and superb handling do the talking. It is also the most dependable car on this list, which is no small thing in a convertible. 

The trade-off is space: the boot is small, and the cabin is snug. If you are not shopping for a family car, though, the MX-5 is an easy recommendation and the best two-seat convertible you can buy.

Pros: Reasonably priced with low running costs, huge fun to drive, brilliant handling, strong reliability.

Cons: Tight interior, small boot, no rear seats.

BMW 4 Series Convertible

Best for: Long journeys with passengers

The BMW 4 Series Convertible pairs quality with genuine practicality in a four-seat package. It is well suited to long trips, with a classy interior and useful storage both in the boot and up front. Recent models also add mild-hybrid technology to the six-cylinder and four-cylinder petrol engines, which helps efficiency. It is not a budget choice, with prices starting from around £55,000, and the options list can climb quickly.

Pros: Practical four-seat layout, classy interior, relaxed and easy to drive, efficient mild-hybrid engines.

Cons: High starting price, only two doors, tempting options push the price up.

Mercedes CLE Cabriolet

Best for: Comfort and a premium feel

The Mercedes CLE Cabriolet puts comfort first, delivering a smooth and genuinely premium drive. The interior is a highlight, packed with technology, and it includes the clever Airscarf system that blows warm air around your neck for open-top driving on cooler days. It is a good family option, but it is not a sports car, and like the BMW, it starts at around £55,000.

Pros: Premium feel throughout, excellent interior and technology, the neck-warming Airscarf.

Cons: High starting price, not especially sporty.

Porsche 718 Boxster

Best for: Pure sports-car handling

The 718 Boxster carries the iconic Porsche look and delivers a driving experience to match. Handling is superb; it will do 0 to 60mph in under 5 seconds, and its mid-engined balance makes it one of the most rewarding cars here. It is strictly a two-seater with limited space, so it is no family car, and you can expect to pay from around £60,000.

Pros: Superb handling, seriously sporty, iconic looks, surprisingly usable boots front and rear.

Cons: Two seats only, limited space, prices start at around £60,000.

MINI Cooper Convertible

Best for: Style at a lower price

The MINI Cooper Convertible offers a fun drive and a cool, characterful interior wrapped in unmistakable MINI styling, all at a more accessible price. It is not the natural family choice: rear legroom is tight, and the boot is small. The roof also takes around 20 seconds to open or close, and only at speeds up to 18mph.

Pros: More affordable, great interior, genuinely fun, distinctive looks.

Cons: Cramped rear seats, small boot, slow roof operation.

MG Cyberster 

Best for: Going electric with style

The MG Cyberster is one of the first fully electric convertibles, and comfortably the cleanest car here on emissions. It covers between 276 and 316 miles on a charge depending on version, and a 10 to 80% top-up takes around 38 minutes on a fast charger. It looks spectacular; the theatrical scissor doors turn heads, and even the entry model does 0 to 60mph in around 5 seconds. The downsides are its fiddly touchscreen layout and a price from around £55,000.

Pros: Fully electric, stunning looks, comfortable to drive, dramatic scissor doors.

Cons: Slow to charge versus rivals, awkward touchscreen controls, punchy price.

The Future of Convertible Cars: Electric Convertibles

Alongside the MG Cyberster, there’s a range of other electric convertible cars on the market today. It’s not surprising with the way the automotive industry is heading - from 2030 the sale of new petrol and diesel cars will be banned in the UK (new hybrid cars can be sold until 2035) and from 2035 all new cars must be zero emission. With that context in mind, here’s a look at some other electric convertibles to watch out for:

Fiat 500e Convertible

A small electric convertible built for the city, priced from around £30,000, which sits near the bottom of the convertible range. The roof folds in around 25 seconds at speeds up to 62mph. The drawbacks are limited space and a range of about 199 miles, shorter than many rivals.

Pros: Fully electric, lower price, ideal for urban driving.

Cons: Cramped, smaller battery range than some competitors.

Abarth 500E Convertible

A sportier take on the Fiat 500e. Similar in price, it drops the 0 to 62mph time to around 7 seconds and produces 162bhp against the Fiat's 115bhp. The catch is range: it manages roughly 164 miles, less even than the car it is based on, though it does charge quickly.

Pros: Fully electric, lower price, sportier than the Fiat.

Cons: Cramped, and a shorter range than the standard 500e.

Maserati GranCabrio Folgore

For a premium electric convertible, this Maserati is the one to covet. It looks sensational, produces around 750bhp, does 0 to 60mph in under 3 seconds, offers up to about 280 miles of range and charges rapidly. The price is the obvious catch, at upwards of £185,000.

Pros: Fully electric, rapid charging, breathtaking looks and performance.

Cons: The price!

Convertible Roofs: What to Know Before You Buy

This is where our workshop experience matters most. The roof is the one thing a convertible has that other cars do not, and it is also the most common source of expensive trouble. A few pointers before you commit:

Soft-top or hard-top?

Hard-tops are becoming rarer. Their main advantages are better insulation, a quieter cabin and a little more security. Soft-tops weigh less and take up less room, which means more boot space and less impact on economy and performance. Most modern soft-tops also open and close in a matter of seconds, often on the move at low speeds.

Roof reliability

Electric roof motors, hydraulic rams, sensors and worn seals are the parts that fail most often. On a used car, always run the roof through a full open and close cycle, listen for straining or grinding, and check the fabric and seals for wear.

Watch the drainage

Soft-tops have drainage channels that clear rainwater away. When these block, water finds its way into the cabin and the electrics, which is a far bigger bill than a routine service. It is one of the first things we check.

If a roof does play up, it very rarely means writing off the car. Most non-operational and soft-top roof faults can be diagnosed and repaired far more cheaply than owners expect, which is exactly the work we do every day.

How to Choose the Right Convertible For You

2-seater or 4-seater? 

If you are carrying passengers regularly or buying for a family, a four-seat cabriolet is the obvious call, and even unused rear seats add handy storage. If it is just you and one other, a two-seat sports car unlocks the best driving cars here.

How much should you spend?

Prices vary widely. New convertibles start in the mid £20,000s and climb well beyond £50,000 for premium and performance models. It is worth budgeting beyond the sticker price, too: the more luxury brands can carry significantly higher running costs, particularly where main-dealer servicing is involved.

Is this your main car and where will you drive it?

How are you intending to use your car? If this is going to be a car for everyday activities, you’re likely going to want a more spacious car that seats more people, and which is comfortable on the motorway and long drives.

If it is for weekends and sunny days, a sharper, sportier two-seater is the more rewarding choice.
