Ronnie Fieg is the proprietor of the fashion label Kith, and he's apparently quite a BMW fan. He's now showing off a restored 1989 BMW M3 going by the name and the matching 2021 BMW M4 Design Study by Kith. They make quite a striking pair in the video above showing the two vehicles meeting, along with lots of other older BMWs.

Fieg's M3 first received a full rejuvenation from BMW in Germany using the company's authentic replacement parts. The exterior wears the gorgeous shade Cinnabar Red. For personalisation, the roundels on the interior and exterior now show "KITH," instead of BMW. The company also fits custom leather upholstery that incorporates embossed Kith logos.

He leaves it mechanically stock, according to BMW Blog. This means there's a 2.3-litre four-cylinder under the bonnet that makes 192 bhp (143 kilowatts) and 170 pound-feet (230.5 Newton-metres) of torque. It runs through a five-speed manual.

The 2021 M4 Competition is also Cinnabar Red, which is not a color in the regular factory colour palette for the new coupe. Like with the E30, the roundels now show "KITH" on them. The Kith-embossed leather also shows up in a few places like the seat headrests and centre console lid.

The M4 Competition is the hotter variant of the new model that makes 503 bhp (375 kW) from a 3.0-litre, twin-turbo inline-six, versus 473 bhp (353 kW) for the regular model. The more powerful variant reaches 60 miles per hour (96 kilometres per hour) in 3.8 seconds.
