- Engine
- 3.0L inline-six, overhead camshaft, ~115 bhp
- Colour
- Dark blue over beige

A rare four-door convertible variant of the Mercedes-Benz 300 'Adenauer', one of only 262 Cabriolet D bodies built during 1952, this matching-numbers example was delivered new to Dortmund in July 1952 and was later registered in Belgium during the 1980s. Acquired in 2012, the car subsequently underwent a comprehensive body-off, nut-and-bolt concours restoration spanning from mid-2013 to late 2017, with sourcing of period-correct components from across Europe. It has covered approximately 40 kilometres since completion.

Maintenance & restoration
- 2013Restoration
Full body-off, nut-and-bolt rebuild carried out to concours standard; only original components in perfect condition were considered acceptable, with parts sourced from Germany, Poland, the Netherlands, and Belgium. Work concluded in October 2017, with final detailing completed in August 2018. The car was refinished in dark blue over beige.
The extended duration of roughly four years was largely attributable to the scarcity of correct original Mercedes-Benz 300 components. Approximately 40 km covered since completion.
