A full load CLS550 isn't as much expensive over a loaded E550. I don't get how a 650GC is $20k over a full load 550xi. Doesn't make sense to me. However I think the look of the 6GC is fantastic and it sure looks/feels expensive (it is expensive unless you are someone thinking $20k is pocket change). Like many others mentioned, I'll take the M5 instead and m5 is a great looking car too.
