3.0 CSi Convertible (1971-1975)

Can you afford a 1971-1975 BMW New Six 3.0 CSi Convertible in 2025?

# 1971-1975 BMW 3.0 CSi Convertible The BMW 3.0 CSi was never officially produced as a convertible by BMW—only the iconic E9 coupe existed in CSi and CSL variants. However, select coachbuilders like Baur created rare open-top conversions, making these among the most exclusive classic BMWs. Powered by BMW's silky 3.0-liter inline-six producing around 200 hp, the E9 platform combined grand touring refinement with athletic handling. Reviewers praise its elegant Karmann coachwork and engaging driving dynamics, though convertible conversions compromise the coupe's structural rigidity. These rarities are infamous for rust issues and expensive restoration costs. Today, they're prized by collectors seeking exclusivity rather than practical classic car ownership. Values have soared, making them investment pieces for BMW purists who appreciate bespoke coachbuilding and want something even rarer than the celebrated CSL "Batmobile."

The 1971-1975 BMW 3.0 CSi was never offered as a factory convertible—only as a coupe. Aftermarket conversions exist but are rare. Genuine models require expensive mechanical fuel injection servicing, rust remediation, and scarce parts. Insurance is costly due to collector status and high replacement values, typically requiring specialty classic car policies.
