The latest BMW M5 keeps splitting opinions online. Some enthusiasts still prefer the previous generation, pointing at the added weight and styling changes of the new sedan. Yet modified examples keep appearing, and the newest one belongs to American rapper Chief Keef.
The artist, born Keith Farrelle Cozart, has been active since 2008 and also goes by names including Sosa, BigGucci Sosa, Almighty So, Turbo, and Otto. His recently purchased BMW M5 now looks far removed from standard factory specification after visiting a tuning shop.

Photos shared by the Instagram account @stars.in.the.ceiling show a sedan fitted with a Stage 2 setup. The modifications include a fresh air intake arrangement and a replacement exhaust system. Updated output figures were not mentioned, though the stock car already produces 717 hp and 738 lb-ft, equal to 1,000 Nm, in combined form.
BMW says the sedan reaches 60 mph, or 97 kph, in 3.4 seconds straight from the factory. Pricing in the United States starts at $123,300 MSRP for the sedan, while the Touring variant costs another $2,000.
The exterior received even more attention than the mechanical side. A forged-carbon appearance dominates much of the build, and while the company behind the package was not identified, the styling strongly resembles Mansory work. At least visually, anyway.
The front bumper now carries extra aerodynamic pieces around the lower section and near the kidney grille surrounds. A revised hood sits above the nose, and the side profile gains extended skirts stretching between the wheel arches. Toward the rear, the sedan adopts a large diffuser and a taller ducktail-style spoiler.

The green finish remains visible beneath the dark forged-carbon surfaces. Black wheels complete the setup, though they still retain a relatively restrained OEM-like appearance compared with the rest of the car.
Inside, the changes continue. The cabin now includes black-and-orange leather upholstery, additional carbon-fiber trim, and a starlight-style headliner displaying illuminated M5 logos. The lighting setup uses multiple colors and spreads across the roof lining in dense patterns.
Some observers will love the transformation. Others, not so much. Still, nobody will mistake this sedan for a stock M5 parked outside a dealership.

One small detail stands out, though perhaps unintentionally. Despite all the aftermarket work, the wheels look surprisingly understated next to the oversized diffuser, forged-carbon body sections, and illuminated ceiling treatment. Strange combination. Yet the whole project seems built around excess anyway, so perhaps subtle wheels were the point after all.
