INFO GUIDE: 1966 Pontiac GTO (Coupe, Hardtop & Convertible)

This identification guide has been drafted for the 1966 Pontiac GTO. For the 1967 Pontiac GTO guide, please click here. The 1966 GTO was the first to be offered as a distinct model, rather than an option package on the Pontiac ‘Tempest’, and featured new styling cues which further distinguished the car from others in the range. The result was particularly positive, with the 1966 GTO recording record sales. 

Today, the 1966 model GTO is a particularly desirable muscle car, with all variants demanding high prices, but particularly so for high specification and original matching number cars. Although a 1966 model may not be difficult to identify on face value, this guide is focussed on providing people with information so they can assess the originality of a particular car, with respect to optional features, modifications, and of course the important ‘matching number’ elements.

This guide provides information on exterior features, interior features, mechanical features, paint colors/codes, as well as detailed chassis and engine number sections applicable to the 1966 Pontiac GTO.
