Yep, that's the letter I got too.
What I wrote:
My girlfriend and I have been lifelong Chevrolet fans. We were extremely disappointed when GM decided to eliminate the F-Body line, which included the Camaro and Firebird, and waited for another car manufacturer to pick up where they left off, i.e., produce a good V8 muscle car. Ford's new Mustang came close to capturing the essence of the 70's muscle car but the new Challenger concept hit the nail on the head! WE WILL BUY ONE IF YOU MAKE IT!
