Found some cars in a couple of episodes of "Wizards of Waverly Place" through a Selena Gomez fan site. I know you don't like to post images from other websites, but I thought I'd throw up the links until I actually decide to scan some myself:
1974 Chevrolet Monte Carlo, from Episode 2.04. Two to three stars:

Checker Taxicab(I thought it was a 1973-82 at first, but I have my doubts), from Episode 2.09. Two to three stars:

Ford Crown Victoria, also from Episode 2.09. One star:

Everything else so far is a background vehicle used between scenes. So while some might be interesting, they're not necessarily worth adding.
Grumpier Old Men is next.
