Mercedes-Benz 111 Coupé 1961–1971 car dimensions: 4880 mm long, 1845 mm wide and 1420 mm high. Unladen weight is 1,410 kg. Braked towing is 1,200 kg.
The cabin offers four full seats with leather upholstery as standard and wood trim accents. Heating and ventilation are fitted. Air conditioning was available as an option on later cars. Instruments use traditional circular gauges. No electronic driver aids appear in the equipment lists.
The boot holds 530 litres with the seats in place. Space matches the saloon closely and suits long trips well.
Braked towing capacity reaches 1200 kg and unbraked 750 kg. Payload sits at 470 kg. Air suspension came standard on the 300 SE versions while later models gained a hydropneumatic rear compensating spring to keep ride height steady under load.
The cabin offers thick wide leather seats with reclining fronts and optional individual rears or sports seats. Extensive wood veneer covers the dashboard instrument housing and speaker grilles with choices of walnut macassar or burl. Leather also trims doors rear shelf and glovebox interior. The pillarless design creates an open airy feel for four adults though rear headroom is limited if fronts are far back. Optional sliding sunroof and air conditioning add to the refined quiet touring experience with independent suspension delivering a comfortable ride.

Fuel comes from petrol inline-six or V8 engines with mechanical injection. Economy figures reported in the 17 to 23 mpg range for six-cylinder models under mixed conditions with higher consumption possible under hard driving or with automatic.
Servicing benefits from mechanical commonality with the more numerous sedans making the cars reliable and straightforward to maintain for specialists. Watch the cooling system especially on alloy-headed later engines and early disc brake setups which can need attention. Regular greasing and oil changes keep them running well.
Safety stands out for the era with a stable passenger cell and engineered crumple zones absorbing impact energy. Front disc brakes were standard from the start with dual-circuit systems and rear discs added later. Padded dash and carefully designed switchgear further protect occupants.
Keeping the car means caring for the high-quality hand-finished leather wood and chrome which define its luxury character. The solid build rewards proper maintenance and the large trunk plus true four-seat space make it practical for classic touring when preserved correctly.
