History
Chassis 2265641 was first registered on 5 October 1973 and sold new through BMW Niederlassung Saarbrücken to Christopher Boch of Hamburg. The original service book survives with the car and documents dealer servicing into the mid-1980s, by which point the car had covered roughly 90,000 km. The car was first registered in the Netherlands on 27 November 1997, and Oldenzaal Classics acquired it in 2021 as an original Verona Red CSi.
The Hartge H6 conversion
Oldenzaal Classics sourced a genuine Hartge H6 engine, a 1984 unit based on the 3.5-liter M30B34 from the BMW 635CSi, identifiable by the H6 stamp in the cylinder head, and fitted it in place of the car's original engine as a deliberate 'hotrod' conversion. The Hartge crank and pistons were transplanted into the original 3.0CSi block, retaining the car's original casting while gaining Hartge's displacement and output. The engine wears a genuine Hartge valve cover and breathes through three new Weber DCOE carburetors on stainless steel headers, and was professionally tuned on a dyno after assembly.
