BMW 4 SERIES COUPE (2020-24) M4 2DR COUPE 3.0 BITURBO 550 GPF SS EU6 CSL STEP AUTO8 is a rare performance coupe near the top of the UK premium sports-car market. This two-door petrol model prioritises speed and driver enjoyment over practicality. The CSL is a particularly exclusive, sought-after version. mycarcheck.com records 123 look-ups covering 39 different VINs, giving a useful snapshot, though not a huge sample. The average recorded private-sale value is £100,100, with mileage averaging 22,000 and annual use around 3,000 miles. Checks show fewer than one previous keeper on average, suggesting many examples have had limited ownership. For experienced drivers, it suits weekend use and occasional commutes, but its two-door cabin, firm ride and running costs limit family appeal. Its 550-horsepower performance, distinctive CSL styling and automatic ease set it apart from rivals such as the Porsche 911, with a more track-focused character, appealing to collectors too.
