2018 BMW M4 Competition Convertible

Description

So, I’ve been keeping this car for a few years now — it’s a 2018 BMW M4 Competition Convertible, and I’m finally selling it. It’s not just any M4, though. I got it directly from the previous owner, and it’s been through a proper BMW health check — clean report, no warnings, all green. That’s a big deal for a high-performance car like this.

It’s Mineral Grey with Silverstone Merino leather inside — a combo that’s not super common, and honestly, looks great. The cabin has carbon fibre trim with black chrome accents, which gives it that sporty but still premium feel. I’ve never driven a car with the M Head-Up Display — it’s a real game-changer, showing you speed, navigation, and other data without taking your eyes off the road.

Under the hood, it’s a 3.0-litre twin-turbo engine making 444 bhp — not the full 450 ps, but close enough. The DCT gearbox shifts fast and smooth, and it gets from 0 to 62 in just 4.3 seconds. It’s ULEZ compliant and averages around 32.5 mpg, so it’s not just a weekend beast — it’s actually practical for daily driving too.

The features are a bit of a dream for a car this class: Harman Kardon sound, reversing camera, high-beam assist, and a full comfort package with wind deflector and warm air collar. I’ve got four new tyres, which means it’s ready to go — no worries about wear.

It’s got both keys, full service history from main dealers and specialists, and a clean MOT through to February 2026. I’ve kept it well maintained, and the 20-inch 666M forged alloys in gloss black give it a sharp, aggressive look that matches its performance.

I live in Swanscombe, Dartford, so it’s a bit of a drive from the city, but I’m happy to arrange viewings or even pick it up if needed. It’s been in great hands, and I’m happy to take part exchanges if anyone’s interested.

The price is £25,155 — it’s not a cheap car, but for what it is, the specs and condition are solid. I’ve always loved driving it, and I’m excited to find someone who’ll appreciate it as much as I have.

If you’re a fan of performance, a bit of style, and a car that actually feels like it’s built for fun — this one’s for you. Just don’t expect it to be a daily commuter — it’s more of a weekend driver, and that’s what it’s meant for.

I’m not a dealer — I’m just a guy who loves cars and found this one after a long search. It’s been a real joy to own and now I’m happy to share it with someone who’ll treat it right.
