[For Sale] 1985 635CSi 5-Speed
Posted: Jan 15, 2025 5:16 PM
1985 BMW 635CSi
Cinnabar Red / 5 Speed Manual / Sport seats
Pearl Beige leather interior
Mileage: 213,500
Asking: $30,000 OBO
I bought this car from a BAT auction in September 2020 for $13k.
I flew to Phoenix from LA and planned to drive it back to Los Angeles. Halfway through the drive, the drive belt snapped and I was stranded for a night in Desert Center. After getting the car back to LA I decided to restore the car above and beyond what a sane person might do, with $49,785.04 of work overall completed during my ownership. The car did not necessarily need all of this work, but I wanted to push the limits of what was possible while still maintaining the comfortable drive of this 635CSi. The original owner also took very good care of the car. Includes all service records since 1985!
Invoices of work completed
Phase 1: Restoration to OEM+ ($16.6k of parts and labor)
