Can you find out what the standard equipment is for the GSR, MR and MR Premium? Take some photos of the catalog if you get a chance (go all double-O spy-shiite man!). I will try to do the same next Thursday or Friday. Don't think I will get very far, but I will try to get my sales person to show me the catalog other people say they have seen.Just a small note. Those codes only apply to the U.S. I believe. The Canadian ones for example started with a C. In Canada there are only three trim levels available. GSR, MR, MR Premium. I ordered an MR and the code was something like CK41 or CLK41 or something. I can't remember exactly. I have to pop in next Saturday so I'll try to remember to look again.
