BMW 4 Series Convertible (2014) | Expert Rating


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 was 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 favor 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 favorably against its major rival, the original Audi A5 Cabriolet. However, later in its life, the 4 Series Convertible had to face much tougher competition in the form of the second-generation A5 and also the Mercedes-Benz C-Class Cabriolet.

No longer on sale, the first-generation BMW 4 Series Convertible holds an Expert Rating of 69%based on 21 reviews published by the British motoring media.

Reliability rating

MotorEasy logo 600x167

The BMW 4 Series has a lower-than-average reliability score, 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.

Nearly a third of all reported problems with the 4 Series relate to its electrical system, with an average repair bill of nearly £400. The other area to look out for is the engine, which accounts for a similar slice of repair claims. The average bill for these was only about £3,200. Engine problems are (unsurprisingly) the most expensive, and unfortunately they seem to be fairly common.

If you’re looking at a used BMW 4 Series, make sure any extended warranty cover you purchase covers all of these potential problem areas.
