Best four-seat convertibles

Put the roof down and bring the family along: these are the best four-seat convertibles

Are you a convertible car enthusiast? Perhaps you, like many of us, have a long list of reasons why you aren't able to actually own one.

If that list includes the fact you have a small family, and as such you have the need of more than two seats - the customary numbers seats for the most popular convertibles on the market - we're pleased to say that you needn't restrict your wish for a convertible any longer.

There are plenty of convertibles that can carry at least four people – and we don't just mean two adults in the front and two toddlers in the back. We've found the best open-top cars that have proper rear seat space.

Most models still require some compromise. For example, you'll often find that there's a reduced practicality as the folding roof requires greater boot space. Headroom can be limited with the roof up but there's an obvious solution to that - as long as it's not raining.


One other consideration is that many four-seat convertibles can't be fitted with wind deflectors when all four seats are filled. This barrier is typically installed over the rear seats. When the side windows are raised, it creates a bubble of air inside the car which considerably reduces the air buffeting when you drive along.

1. Audi A5 Cabriolet

Used Audi A5 Convertible deals from £12,950
Monthly finance from £206

The Audi A5 Cabriolet is a classy convertible, combining solid build quality, powerful engines and a superb interior. As well as the high-tech options available in the A5 Coupe, the Cabriolet has some unique features, including microphones in the seatbelts for clearer hands-free phone calls and a neck-heating system.

The roof is made of several fabric layers to reduce noise when it's up. It folds in just 15 seconds, while you're driving at speeds of up to 31mph.

Space in the back is reasonable but headroom is tight, at least when the roof is up. The boot is impressively large though: 320 litres with the roof down or 380 litres with it deployed.

It’s not the most nimble of convertibles, but the A5 is more of a cruiser than a sports car, so it does absorb the bumps well. Like most convertibles, you can feel slight wobbles in the car's structure because of the lack of a fixed roof, but it’s nothing serious. Audi’s 2.0-litre TDI Ultra diesel engine is a cracker: powerful, smooth and frugal.

2. BMW 4 Series Convertible

Used BMW 4 Series Convertible deals from £14,500
Monthly finance from £219

The BMW 4 Series Convertible has a metal folding roof as opposed to a fabric one, which makes the car quite heavy and certainly not as sprightly as its lighter and stiffer coupe equivalent.

The advantage is that it's much quieter when the roof is up, and the car is more secure too.

Given the 4 Series Convertible's weight, the diesel engine is a good choice, for its stronger pulling power, which makes accelerating away feel smoother and less strained.

It's a handsome car too, with an equally attractive and well-built interior. There’s plenty of space in the front while legroom is pretty generous in the rear. Headroom at this end of the car is pretty tight, though, when the roof is up. The boot is a decent size at 370 litres but when the roof is down, this shrinks to 220 litres.

3. Mercedes C-Class Cabriolet

Used Mercedes C-Class Cabriolet deals from £20,600
Monthly finance from £317

Back to a fabric roof, this time with the Mercedes C-Class Cabriolet.

Here, extra support has been added the the chassis to take into account the loss of rigidity due to the absence of a fixed roof compared. This has eliminated most wobbles in the car's structure, but adds 120kg to the car's weight compared with the coupe version.

This does mean that the C-Class Cabriolet crashes into potholes with more force than the fixed-roof Coupe, but this can be fixed by opting for the optional air suspension, which restores the smooth ride.

The interior is as stylish as the exterior, with lots of artificial leather and aluminium. Sat-nav is standard but the dashboard screen is not quite as intuitive as BMW’s equivalent.

It has the company’s Airscarf neck-warming system as standard. Front seat space is generous but those in the back won't feel quite so well provided for, since head and legroom are in short supply. A 4 Series is roomier.

Roof up, the Mercedes’ boot is bigger than the BMW’s and can be made larger still by dropping the rear seat backs. However, folded, the boot is much smaller.

4. Range Rover Evoque Convertible

It’s not especially cheap, but if you're looking to make a statement, then the Range Rover Evoque Convertible certainly stands out.

The Evoque convertible sport utility vehicle (SUV) is the only car of its type on the market thus far, although a convertible version of the VW T-Roc is due on sale in 2020 to provide some competition. It retains the rugged off-road ability of the standard Evoque – so it can drive through water that's half a metre deep, crawl up and down mountains, and navigate deeply rutted tracks. Yet It’s also perfectly happy cruising around town or out on the motorway.

Because the convertible was designed after the other versions of the Evoque, which means that it's quite compromised, with a small boot that has a tiny letterbox-shaped opening, and extra support to make the car more rigid, which increases the car's weight noticeably.

As a result, it doesn't feel sporty or nimble: it's best to put the roof down, cruise along smoothly and soak up the glances - admiring or not.

5. Mercedes S-Class Cabriolet

Used Mercedes S-Class Cabriolet deals Limited stock

If you’re looking for the ultimate in opulence for your four-seat convertible, the Mercedes S Class Cabriolet probably offers the most luxurious experience outside of a Bentley or Rolls Royce.

Its elegant, swoopy bodywork wraps up an interior that’s crammed with high-tech gadgets, beautifully finished trims and expensive-feeling leather. It’s no sports car, but it is a magnificently refined cruiser, and AMG versions are stupendously fast.

The only significant compromise you’ll have to make is the rear seats, which are a little cramped when the roof is up – but there’s still plenty of space for the occasional occupant.

6. Ford Mustang Convertible

Even people with very little interest in – or knowledge of – cars will know what a Ford Mustang is. It is the ultimate good-time cruising convertible, a slice of pure Americana. The current generation is also the first to be offered in the UK with right-hand drive.

Compared with a Mercedes, BMW or Audi convertible, the Mustang delivers loads of equipment for the money, and the big V8 petrol version is fast and sounds great. Coupled with either a six-speed manual gearbox or a slick 10-speed automatic, it makes the Mustang a joy to drive.

The interior isn’t as classy as you’ll find in a BMW or Mercedes, and access to the rear seats – as well as the space in the seats themselves – is a bit tight. But when the sun’s out and you’re cruising down your favourite road, none of that will matter.
