Summary


The BMW 4 Series Convertible is the drop-top version of the 4 Series Coupé. This is the first-generation model, which first arrived in the UK in early 2014 to replace previous models badged 3 Series Convertible, and ended production when the latest iteration of the 4 Series launched in 2020.

Reviewers agreed that the 4 Series Convertible was a capable top-down cruiser that could provide a quiet and relaxing driving experience, as well as high-speed wind-in-the-hair thrills on request.

“It’s a quick and comfortable luxury car for rolling up a sun-drenched coast”, Auto Trader concluded, after praising the drop-top for its metal folding roof, which takes around 20 seconds to raise or lower. Incidentally, the latest 4 Series has ditched the folding hard top in favour of a traditional soft top.

However, the addition of this roof mechanism adds weight to the car, which in turn affects the convertible’s performance and driving dynamics. “It feels heavier than the coupé”, Parkers says, also commenting that the roof reduces the boot space. Carwow argues that, due to this added weight, the convertible is slower than its coupé counterpart, as well as being more expensive.

The 4 Series was well-equipped as standard and compared very favourably against its major rival, the original Audi A5 Cabriolet. However, later in its life, the 4 Series Convertible had to face against much tougher competition in the form of the second-generation A5 and also the Mercedes-Benz C-Class Cabriolet.

As of April 2024, the first-generation BMW 4 Series Convertible holds a Used Car Expert Rating of C, with a score of 61%.

Reliability data provided exclusively for The Car Expert by MotorEasy

All data based on MotorEasy average workshop costs for extended car warranty claims

The BMW 4 Series has a reliability score that’s about average, according to exclusive extended warranty data provided by our partners at MotorEasy. This score covers coupé models as well as convertibles – from this generation (pre-2020) version as well as the current (2021 onwards) version.

A quarter of all reported problems with the 4 Series relate to its engine, with an average bill to date of an eye-watering £2,000. Gearbox problems are similarly expensive, although they seem to be quite rare to date. Suspension and braking problems are also common, although the repair bills are much more reasonable.
