Isdera
Commendatore 112i

Why it matters

The Commendatore 112i was meant to succeed Isdera's Imperator 108i as a more thoroughbred GT with a 6.0-litre Mercedes-Benz V12 mid-mounted behind gull-wing doors, and to be the basis of a Le Mans entry. Isdera built the one car, a hand-built prototype, and it remained unique.

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

Eberhard Schulz, who had founded Isdera in 1982, unveiled the car at the 1993 Frankfurt motor show, named in honour of Enzo Ferrari. A limited series was planned, but funding from Japan was hit by a downturn that year and the company was restructured, ending the Le Mans plan. The car was sold in 1999 and shown under the name Silver Arrow; Isdera re-acquired it in 2016 and restored it to its 1993 specification, with fewer than 10,500 km covered at its 2021 sale offer.

A second tubular frame dating from 1987 was kept at the works and later completed by an enthusiast, but the factory states there is only one original Commendatore 112i.

Identification guide

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

The original car has a fibreglass body over a spaceframe, gull-wing doors and engine covers, a roof-mounted periscope mirror, pop-up headlights from the Porsche 968, BBS two-piece wheels and Porsche Arctic Silver paint. Between 1999 and 2016 it carried side mirrors, five-spoke wheels and a Silver Arrow name.
