When were the new 1967 Z/28 released

[1967Z28]

The first '67 Z off the production line was built on 12-29-66 with fifteen more built the following day. For some reason, there was a shipping delay for most of these cars of around two weeks. Roger Penske was frustrated by the lack of a prompt delivery and sent his good friend George Wintersteen to pick up the car at the Norwood plant on 1-10-67 and drive it (sans heater or radio) to Penske's shop in Newtown Square, PA outside Philadelphia. That's the earliest I know of a delivery to an actual customer. Most of the other 15 took up to week more to get to the dealership. Chevrolet did not do a good job of promoting these cars and didn't think they were going to be a big seller in '67. Rather than using company advertising dollars, they were hoping to sell them by word of mouth through newspaper articles (like the one above), a few magazine road tests, and racing coverage in publications such as Competition Press & Autoweek.
