I own a Coure CX CNG, I almost always run it with A/C never had a heating problem. The cooling has been very effective even in the month of May/Jun.
The differences between CL and CX (when I checked before booking mine in Sep 2005, got it in Feb 2006)
CL didnot have AC, matching bumper, no choice of metallic colors and Deck. I dont remeber exactly but there were couple of more differences. They had discontinued CL back then but I hear they hav restarted it. U can check the latest from
