In the opening credits they are all in a Jeep Wrangler type vehicle, and they come to the Sign welcome to Port Washington population 9,338. In the first few episodes Carol never had a Jeep Wrangler she had a run down Station Wagon that keep breaking down, so Frank told her he knew a guy and they all went to look at cars at a car dealership. Frank thought he could get a good discount since he sort of knew someone at the dealership, but Carol ends up getting the discount.

How can that vehicle be in the opening credits if she never had it until a few episodes later?
