April 15, 2006 at 700am PDT. History channel is broadcasting "Automobiles" featuring "Nissan Z Car". I used TiVo to search.

unless you have Directv, then it's at 4AM PDT (channel 269)

On Saturday, April 15th, I get to watch Dream Car Garage on SpeedTV at 6:30 AM, and then change the channel and watch the Z car special on the History Channel at 7:00 AM. I'll be in my PJ's eating a big bowl of Count Chocula with a smile on my face
