- Desirable Highline spec with full leather interior
- Updated M30B35 3.5 litre straight-six
- Honest mileage ready to be enjoyed
Few shapes in BMW’s back catalogue carry the same authority as the E24 6 Series, and in Highline form, the 635CSi represents the model at its most complete. SB is thrilled to be listing this 1989 635CSi on the platform that sits towards the end of E24 production and presents exactly as you’d hope: understated, well-kept, and retaining the kind of honest, usable charm that makes these cars so appealing today. Finished in Diamond Black Metallic over a full Silvergrey leather Highline interior, it carries all the hallmarks of a properly sorted, enthusiast-owned example and is just the kind of car we love here at SB. With 165,000 miles on the odometer, this is not a garage queen, but that’s precisely the point; the improved M30B35 straight-six is renowned for its durability, and cars like this reward regular use. The E24’s shark-nose profile remains one of BMW’s most iconic designs, and this example wears it well. The bodywork presents with a clean, straight appearance that suits the car’s understated character. The panel gaps appear consistent, and the car sits well on a set of multi-spoke alloy wheels that complement the long, low proportions without looking overdone. But it's the Highline specification where this car really distinguishes itself as the cabin is trimmed extensively in leather. Not just the seats, but also the dashboard and door cards that makes this example feel far more special than a standard E24. Here's your chance to own a piece of history that is ready to be used and enjoyed as intended without hesitation nor concern.
