What exactly is wrong with it? What is it doing that is should't be? What is it NOT doing that it SHOULD be?

We need some sort of description of what you want your code to do.

[keskiverto]

For example, if the code does not compile, then you should tell the exact compiler error(s). (In the long run you should learn to read them yourself too.)

getDisplay() is a member function of class Car. It needs to be called on an object of type Car (which you haven't actually created yet).
