Petrov is a greenish Zaporozhets car who is part of the Trunkov family that works with Professor Z. "Petrov hails from a tiny village on the Baltic Sea where temperatures in winter drop down to a frigid -10C. And if that's not enough, the salty air and rocky roadways have irreversibly corroded his body panels. But Petrov really doesn't mind. In fact, he likes his engine air very cool, and thinks the bubbling rust makes him look more 'mileage mature'. Add the fact that he carries most of his weight in his rear-end and it's a wonder he doesn't break in half when the going gets rough."
