Well, I will congratulate you on your purchase. I haven't personally driven a Genesis Coupe and the only place I see them regularly is on the The Price is Right.
Don't know about markup, but if you couldn't afford the Camaro SS, you couldn't afford the 370Z some were suggesting either as it costs more than my SS. I sold my 2007 350Z waiting for my Camaro to be built.
Sorry you couldn't get into a Camaro right now, but hope to see you in a couple years wearing your "permagrin"... Best Wishes..
