To answer your question about the schedule for next year (2007), email TRG.
As far as the GTO.R goes, I asked the guys over at the Rolex Grand Am Headquarters that same question about: longevity of certain makes. The officials at Rolex said, that their rule for makes is about the same as NASCAR, "The teams can field a 2006 model year vehicle for three years after production has ceased". They also informed me that, in certain circumstances they can even alter that rule to help the teams out, by extending the time use beyond three years. I passed this info along to the guys over at TRG (Kevin Buckler) and he said he would pass along the info to his staff.
The other option as far as cars out there for TRG to use may be the new Camaro. I passed this suggestion along incase GM continued to drag their feet (as we all know GM has a tendency to do). Next year, a team or two may field a Mustang. TRG should be ready, any team that wins a championship in a heavier car (which at times was handicapped with the officials adding weight) will be ready.
Look at it this way, at least TRG will be staying in the GM family if they go with a Camaro, they are just changing sheet metal is all. The GTO has always been a larger car anyway.
Let's just hope GM doesn't drag their feet, it will be nice to contiue seeing GTO's winning championships.:gears:
