The GTOAA Concours Modified Judging Standards are published to serve as a guideline for GTO enthusiasts who enter their vehicles in Concours level shows at GTOAA National Meets and GTOAA sanctioned Regional Meets. This publication is an attempt to standardize judging procedures for modified Pontiac GTO and Pontiac A-Body and X-Body automobiles manufactured from 1964 – 1974. The GTOAA acknowledges that these standards may not satisfy every vehicle owner’s requirements, so we challenge you to provide the GTOAA Concours Committee with constructive feedback so that we can continually improve our judging techniques. These modified judging standards are intended to be a dynamic document that is updated periodically as our sophistication in evaluating these vehicles evolves.

The judges are instructed to use their discretion when it comes to discrepancies from normally accepted practice. It is the owner’s responsibility to point out differences and provide any documentation to judges so proper points can be awarded.

Some enthusiasts may opt to restore their vehicle back to the exact way (or as near possible) it looked when it rolled off the assembly line. Others may choose to modify their vehicle from stock, customizing the vehicle to their liking. Whatever the goal, the GTOAA encourages you to follow standards of workmanship, safety, and restoration accuracy. The standards for the Concours Modified vehicle class are outlined in this manual.

The bottom line for all GTO owners is enjoyment – enjoyment in driving your GTO, in showing your GTO, or in racing your GTO. Additionally, there is a certain amount of nostalgia in that enjoyment because you know that in the history of the automobile, there will never again be an era as exciting as that ushered in by the high-performance muscle of the GTO.

A special thank you goes out to committee members Jon Wacholtz, Paul Freese, and Doug Pulskamp who contributed to the development of this document. Thank you also to all the GTOAA technical advisors and members that submitted information to assist the committee with this project.
