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

History

Octane reports that research by Martin Kent led the International Lamborghini Registry to accept the Monza car as a 400GT Interim, of which 23 were built with standard bodywork. The car has the 4.0-litre V12 with a Lamborghini gearbox and differential.

Identification guide

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

Interim cars differ in drivetrain detail. Some have the Salisbury differential, while others have the official Lamborghini unit, so the axle should be checked rather than assumed.
