Judging Standards


Car Show Judging

Guidelines and Definitions

This document is meant to help contestants prepare for show competitions, and to help answer any questions, about shows that are sponsored or judged by the GTA car club.

There are two major types of car show competitions, Appearance judging and Concours judging.

Concours events usually are conducted with a specific type or make of automobile.Judging categories consist of authenticity and workmanship.Concours events depend upon judges who are experts in the type or make of automobile being shown.A large percentage of points may be awarded for such items as, options that match build sheets or the VIN, as well as such small items as correct trim screws or inspector markings in the correct locations.Many concours events require the owners to produce documentation to prove authenticity and provenance.

Appearance events mainly focus on the workmanship of the particular Automobile being shown, with a minimal regard for authenticity.Automobiles are grouped into classes composed of similar types, and years of production, to facilitate judging; comparing apples to apples.The authenticity of the automobiles is not in question, except when an automobile clearly falls outside the criteria of the specific class. This type of event is much easier to judge and is more compatible when cars of many different makes, models, and years are shown against each other. The GTA makes every effort to allow each contestant to choose the class which they feel their automobile should be shown.

All car shows hosted or judged by the GTA car club are of the appearance type event.It is beyond the scope and expertise of the GTA to sanction concours type events.

Each Judge only looks at one category per show, and categories are rotated among club members.The Head Judge Tallies individual category scores to arrive at a point total.Every effort is made to be fair, and all decisions are final.The GTA car club asks every contestant to display good sportsmanship.Judging sheets are given to each contestant at the end of every show.
