Got my letter today too.
Following is the text:
Thank you for ordering your all new 2010 Chevy Camaro. Progressive in design, engineering amd technology, Camaro is the 21st Century sports car. But bold words and superlatives can't truly capture the soul of Camaro. And you know this well - it's why you reserved yours and can't wait to slide into it's driver seat.
Your enthusiasm is fueling us to deliver a vehicle that exceeds your dreams. And rest assured, we are working full speed to fulfill your request.
You'll be hearing from us soon. Thanks again
North American Vice President, Chevrolet
