Aston Martin
Vantage Pininfarina Speciale AM3 / AM4

Why it matters

AM3 and AM4 are two bespoke 2+2 coupes that Pininfarina designed on Vantage 600 chassis for the Sultan of Brunei. Five design studies, AM1 to AM5, were submitted but only AM3 and AM4 were built, in three examples each, and none was shown to the public.

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 project began when the client asked Pininfarina to approach Aston Martin with a proposal for unique cars on Vantage mechanicals. Scott A. Barras drew the AM3 in 1995. Aston Martin supplied unnumbered rolling Vantage 600 chassis with the twin-supercharged 5.3-litre V8, and Coggiola near Turin built the aluminium bodies and Pininfarina-specified interiors.

Three AM3s were built between 1996 and 1997 and three AM4s followed, the latter completed in early 1998. All were delivered directly to the Sultan's collection.

Identification guide

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

AM3 has a composite detachable nose cone integrating the lights and a recessed intake, a smoked black rear panel in the outline of the Aston grille, a Kamm tail with dual circular exhausts, and six-spoke wheels. AM4 has an elongated five-slat grille, DB7-type headlamps, bonnet air outlets, a rear light cluster with an inverted grille shape and dual rectangular exhausts. Both use unnumbered Vantage 600 chassis, so there are no standard Aston chassis numbers.
