Two things wrong: First, your indentation is off. You can't create a new object, inside of defining what that kind of object is. That's not a good way of wording it, but a python design choice is that everything indented after a colon is inside of that if statement/function/class/etc.. (Also not a good explanation.) Basically, unindent
this line, and then you need to write pass inside of the class Car(object): because that's a keyword that kind of place holds. It tells python to ignore the fact that nothing is inside of something that would typically need something inside of it to define it.
I hope that you got something out of this, it's very late so i'm probably not sounding too bright.
