The BMW M4 CSL was produced in 2022 and 2023. Global production was capped at 1,000 cars. In the UK, just 100 right-hand-drive examples were allocated.
The starting point was the M4 Competition already one of the most capable performance cars BMW has built in the modern era. BMW's M division then removed 100kg through the deletion of rear seats, the fitment of a carbon fibre bonnet, carbon ceramic brakes as standard, and lightweight bucket seats. The power went up to 550 horsepower. The 0-62 time dropped to 3.6 seconds.
New, with options, UK cars cost £130,000 in 2022. Today, you can buy one for around £85,000.
That is a £45,000 loss for the first owner in three years. Painful. But it creates something interesting for the second buyer.
The E46 M3 CSL Parallel
The original E46 M3 CSL was not immediately recognised as the icon it has since become. In the years after the G80 M3 and M4 arrived, E46 CSL values softened. Examples traded as low as £35,000 for cars that had been driven hard and specified poorly. The mainstream market had moved on.
Then something happened. The collector community started to examine what the E46 CSL actually was: one of 1,383 cars, the most focused BMW M car ever built for the road, naturally aspirated, lightweight, irreplaceable. Values started moving. They moved through £50,000, through £80,000, through £100,000. The finest examples now sell for over £160,000.
The M4 CSL is not the same car. It is turbocharged, heavier, and built in an era where the parameters of performance car development are fundamentally different. It will not, in all probability, appreciate to the same extent.
But the structural parallel is real. A limited-production BMW M CSL, built in small numbers, initially depreciated by first owners who paid a new car premium, now available to a second buyer at a significant discount to that premium. The question is whether the second owner's entry point is sufficiently below the long-term collector value to produce a return.
The Case For the M4 CSL
1,000 cars globally. 100 in the UK. A turbocharged inline-six producing 550 horsepower in its lightest, most focused configuration. The last M4 CSL of this generation. BMW will not produce another run of CSL variants on the G82 platform.
The M4 CSL also has something the standard M4 does not: a fixed production number and a clear collector identity. Standard M4 Competitions depreciate freely because BMW builds them in large numbers and the market is always supplied. The CSL is a different asset.
At £85,000 today, the M4 CSL is significantly below its new car price. Whether it recovers to that level, or beyond, depends on how seriously the collector market prices the 1,000-unit production cap and the CSL lineage over time. The early evidence — values stabilising rather than continuing to fall — suggests the floor has been found.
The Honest Assessment
This is not a guaranteed appreciating asset in the way the E46 CSL has proved to be. The turbocharged powertrain, the modern electronics, and the weight relative to the original CSL mean the collector case is more nuanced. But mispriced and misunderstood are not the same as wrong. At £85,000 for a 1,000-unit production BMW M CSL, the risk-reward looks more interesting than the mainstream market currently suggests.
