The 2003-2004 BMW M3 CSL (E46) is a stripped-out, track-focused version of the iconic M3, with only 1,383 units produced. Reviewers and enthusiasts universally praise this lightweight legend for its raw, visceral driving experience, supreme agility, and unique carbon-fibre airbox which gives its uprated 3.2-liter S54 straight-six engine a characteristic intake sound. It is famous for pioneering carbon-fibre-reinforced plastic components in a production M car, achieving a weight reduction of approximately 110 kg (243 lb) over the standard M3. Today, the CSL is highly sought-after, commanding high prices, and is best suited for collectors and dedicated track-day drivers who value pure, high-performance motoring.
BMW M3 ownership includes high maintenance costs, averaging $14,868 over 10 years, and a high probability of major repairs (41.71% in 10 years). Reliability issues include rod bearings and VANOS. Insurance is also typically high, ranging from $217 to $441 monthly.
