Maybe you just need a small sedan. It will have a lot less cabin space than your PT Cruiser. A Chevy HHR is analogous to your PT. It is also a Cobalt station wagon. If you want a new car, try a Chevy Cruze, Ford Focus, Mazda3, or something similar. Rent one for a weekend and sit an adult in the back to tell you when it cools off on one of those 100+ days. If you want a station wagon type vehicle, you have to get a larger one Like a Pilot or Explorer.
