Everyone should keep in mind that ITE ("Enduro" or "Endurance") is "Improved Touring" in name only. It was a class offered by some regions (started in the Southeast, yes?) as a "catch all" place for outdated Firehawk-like cars to play. It was simply given the IT moniker as a means of convenience.

In no way would I recommend trying to incorporate ITE into the National/GCR rules set. There are far too many variants/rules/allowances among prepration options for this group to even be remotely considered Improved Touring in philosophy or implementation.
