BMW M5

This F90 BMW M5 has been taken well beyond the factory's 592 bhp. It is a heavily modified car, built around an RK Autowerks forged 4.4-litre V8 with Carrillo rods, CP pistons and a balanced crank. The page claims more than 1,000 bhp, though that figure is based on similar builds that were dyno-proven. The listing quotes Dragy-timed runs of 2.54 seconds from 0 to 60 mph and 19.37 seconds from 100 to 200 mph.

The work reportedly cost about £80,000 and appeared on the cover of Performance BMW Magazine in August/September 2021. Other changes include a GruppeM carbon intake, water-methanol injection, a custom Utku calibration and an unnamed upgraded twin-turbo setup. The chassis gets an AC Schnitzer exhaust and lowering springs, with 21-inch AC Schnitzer wheels on Michelin Pilot Sport 4S tyres. The car also has BMW's carbon-ceramic brakes.

It is finished in white, with an eight-speed automatic gearbox and xDrive all-wheel drive. It has covered 64,000 miles. Standard equipment includes a carbon roof, head-up display, Harman Kardon audio and a four-zone climate system. The page gives no registration or owner count.
