I'm heading north tomorrow to look at an 09 GT/CS, and had a couple questions that have me puzzled. I'm looking at pics and specs online and seeing differences in the GT/CS models. What is the difference between the GT and the CS? I read that the CS has badges inside the vehicle that are chromed, decals on the side,and the front and rear fascia are different? The car I'm looking at tomorrow does not have the side stripe, no hood scoop? "Some 09's seem to have them and some don't?" is there anyway of knowing for sure if this is a CS model without it being obviously cosmetic?
