Which end is the front? This little car gave its passengers two very different views.

Reveal the auction result
Based on a completed sale at RM Sotheby's, an estimated value for this vehicle is $51,750.
Why this sale: Exact 1958 German-built Zündapp Janus, identification W3571, with the production 248 cc single-cylinder two-stroke and four-seat double-ended body; not a Dornier Delta precursor, motorcycle or different microcar. RM described the car as fully and professionally restored to factory-correct specification and exceptional throughout. The restoration and rarity are value-positive differences from unrestored, incomplete or driver-quality Janus examples.
RM's displayed $51,750 sold result includes the auction's 15% buyer's fee; taxes, registration, transport and later work are excluded. One auction result is a reference, not an appraisal; condition, history, options, location and market timing can change value. Accepted as an exact-year, exact-model completed sale from RM's Bruce Weiner Microcar Museum auction. The RM results identify it as lot 248 in the Friday 15 February session. Searches did not establish a newer primary identity-matched completed result, but this is not claimed to be globally latest.
More than a set of wheels.
Zündapp was known for motorcycles when it tried a small family car. Its Janus used a design developed from aircraft designer Claudius Dornier’s idea. The front passengers faced forward, while the rear passengers watched the road disappear behind them. The 1958 car belongs to a short production run that began in 1957.
Look a little closer.
The two benches could be arranged into a sleeping surface, making the tiny Janus a very small camping companion.

Two ends, two viewpoints
Janus took its name from a Roman god associated with beginnings and endings. The museum highlights its four back-to-back seats and nearly matching front and rear shapes.

Zündapp sought outside designs as customers wanted more substantial transport. It selected Dornier’s double-ended car, but sales disappointed and production lasted only about a year and a half.

Look at the doors as well as the badge. The Dornier precursor used top-hinged end doors; Zündapp changed to side-hinged doors for the production Janus. A museum photograph or filename alone therefore cannot establish that a car shows production Janus equipment. The gallery cabin photograph is labeled as model-level context because its exact year is undocumented.
