Mercedes-Benz
600 Coupé (W 100) one-off

Why it matters

The 600 Coupe of 1965 is a single two-door prototype built by the Mercedes-Benz testing department on a shortened 600 chassis. The archive describes it as single-piece production not designed for sale. It is the only coupe in the W 100 range.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The coupe was built in August 1965 as a prototype with a wheelbase of 2980 mm, against 3200 mm for the 600 saloon. After a period in the testing department it was sold in the USA. It returned to Germany at the beginning of the 1990s and, according to the archive, is now in a private collection after full restoration.

Identification guide

How to tell an original from a replica or later conversion.

As a unique prototype, the car is identified by its two-door body and dimensions: 2980 mm wheelbase, 5320 mm length, 1950 mm width, 1485 mm height and a kerb weight of 2450 kg. It uses the standard 6332 cc M 100 engine (code 100.980), air suspension with level control and four-wheel disc brakes, and it was never offered with a list price. Any claim of a second 600 coupe should be tested against the archive statement that one car exists.
