Despite our weather, we love convertibles in the UK and while there are plenty of two-seat sports cars around, there are fewer options if you want four seats and some practicality.

The BMW 4 Series Convertible ticks the boxes for those desiring performance and comfort, along with the joy of open-top motoring. It's one of the best convertible cars around. As we'll explain in our BMW 4 Series Convertible review.

Four-seat convertibles always look like a great option. After all, who doesn’t want to be able to share the open-top, wind-in-your-hair experience of a convertible with friends?

The trouble is those back seats often don’t have much legroom, so unless you are just driving your friends home from a night out, they aren’t going to be so friendly after having their limbs squashed in.

The BMW 4 Series Convertible and the 3 Series before it have always been popular choices, providing reasonable legroom for those in the back unless a tall adult is in the driver’s seat. It’s a potential family car option too, with room for the kids, decent space in the boot and a good level of comfort.

The latest generation of BMW 4 Series Convertible arrived in 2019 and with it came the buck-toothed grille. We don’t mind saying that we aren’t fans, but we are getting used to it and one person’s ugly is another person’s beautiful. So let’s just leave it at that.

The BMW 4 Series Convertible is a great all-rounder, delivering supple comfort around town, then rewarding the enthusiastic driver with typical BMW driving dynamics beyond city limits.

Plus it has space and practicality for four. BMW has dropped the diesel engines and the petrol 430i from the range, leaving the 420i as the sensible option, then the performance pairing of the M440i and M4 Competition.

It doesn’t have too many similar-sized convertible rivals, with Audi having dropped its A5 Convertible and the Lexus LC costing over twice as much.

There is the Mercedes-Benz C-Class Cabriolet, although this will be replaced by a CLE convertible in 2024 (which brings together both the C-Class and E-Class drop-tops in one model). Alternatively, there are plenty of two-seat sports convertibles on the market if you decide you don’t really need the space.

What's the best four seat convertible with four-wheel drive?

"My daughter's four year lease on a Range Rover Evoque ends in March 2024. She is looking to replace it with a four-seater convertible and doesn't want an EV. Her annual mileage is about 12,000 miles. As she lives in Sheffield, built on seven hills and prone to snow in the winter, four wheel drive would be preferable. What makes and models should she be looking at, and are there any new models due out to be available by Spring 2024?"
There are a very limited number of four-seat convertibles that are also available with four-wheel-drive, so right now her choice is likely between the BMW 4 Series Convertible with xDrive or the Mercedes-Benz E-Class Convertible with 4Matic. If she would rather choose from a wider range of vehicles, an alternative would be to purchase a second set of alloy wheels with winter tyres, which would arguably offer more security in snowy conditions than four-wheel-drive.

Are run flat tyres more susceptible to sidewall damage?

"My BMW 428i Convertible has just completed 30K miles - I "celebrated" by buying the 4th & 5th new run flat tyres - all of which have been replaced due to damaged sidewalls. I have never hit any obstruction, it seems that the tyres cannot deal with current driving conditions. In over 50 years of car ownership I have never replaced a tyre with a damaged sidewall on any other car. Is this a common problem? Can I fit conventional tyres to the current wheels?"
Run flat tyres have stiffer sidewalls to prevent deflation in the event of a puncture, but the result of this can be that they are less capable of dealing with bumps and potholes as they lack the same flexibility as regular tyres. You can fit conventional tyres to your car without any problems, although you may want to invest in a tyre repair kit or better still, a spare wheel and associated tools to deal with a possible puncture.
