For the last 5 years I've had a large SUV (GMC Acadia) and well we are moving and I'm going to start commuting so I need something that gets better gas mileage. I will have 2 car seats (one FF the other RF) so I need something that will accommodate them and the front seats comfortably. What do you have and love or what do you hate?

(Note: looking for mid-priced not luxury, that's not in our price range.)
