1980 BMW 635CSi 6-Speed

This slicktop 1980 BMW 635CSi is a European-market example that was refurbished before being sold through by Oldenzaal Classics and imported in 2025, after which it was fitted with an S54 3.2-liter inline-six and six-speed manual transmission by Lang Racing Development. The engine installation included rebuilt cylinder head and VANOS components, new timing-chain components, oil pump and bearings, fabricated engine mounts, headers and exhaust, a custom intake, and associated wiring and control hardware. The drivetrain uses an E46 six-speed transmission, a limited-slip differential, and a custom M3 driveshaft. The car also features 15″ BMW Style 5 wheels, a decklid spoiler, fog lights, European-market lighting and bumpers, power windows, and power locks. Now with an indicated 147k kilometers (~91k miles), this E24 635CSi is now offered on dealer consignment with a clean Oregon title. The selling dealer believes the exterior color is Graphite Metallic/ Graphit (087), and the car features fog lights, decklid spoiler, and twin center-exit exhaust outlets. The seller notes chips and blemishes in the paint, and European-specification lighting and bumpers have been retained.
