If you want to know about the HHR, let me know. I drive it 80 miles a day and LOVE it. Even with a lead foot I get 26-27 MPG from it. Just notice that the HHR and Cobalt SS recommend premium. This is a heated debate on www.ChevyHHR.net, but most just use premium. Just pointing it out since the co. is paying for the gas it may be a point of contention.
