Same car.

TV can mess with certain colors.

That's why the Nash Bridges 71 cudas were that wierd school bus mustard yellow color

The pilot was shot with the cars in curious yellow. And it looked bad on TV. A club member worked in the "edit industry" and told us about it when it went down. They had to repaint the cars and re-shoot scenes. Julius in the club worked on them after that and a did few things during the run when the cars were primarily in Bay Area.
