1957 BMW 507 (first series)
- Colour
- Sea green with black hardtop

Chassis 70044 is a first-series BMW 507 produced in July 1957, one of only 252 examples built before the model was discontinued in 1959. Delivered new to a Munich dealership and originally finished in off-white with red leather, it passed through just three owners before its 2014 acquisition, with its third owner retaining it for over half a century. The car still carries its original engine and approximately 73,000 kilometres of documented use, making it an unusually unrestored survivor of one of BMW's most celebrated designs.
