The only thing that really sets it apart is the front grill. The cars being made nowadays are all shaped in wind tunnels so they pretty much all look the same in dimension and basic shape. Heck, I like the Audi A4, but it looks disturbingly like a Honda accord from a side profile for much the same reasons. And that's exactly what the US automakers are aiming for - not to be different - they want to mimic the best sellers in the industry. It's to the point where everyone is making their generic 4 door sedan, coupe, truck, etc and unless you really invest your time, it's hard to even notice or care about whether this one has chrome on that arch or not.
Gone are the heydays of significant styiling risks - this isn't the 50's when you'd get the kind of significant "just because" styling... maybe if it's just easier if I show you. Here are some past examples of major styling departures that were worth the exaggerated reactions...
I could go on for a while but you get the point. Which isn't to say that I like every major chance that a car manufacturer has taken, but those were major departures worthy of the "oh my" reactions. Also, I used the newer gull wing mercedes in case anyone thinks Im stuck on old cars - I'm not. I like the new ones just as much.
The CTS is a good car, but it's pretty much just another bland 4 door sedan at least in shape and form, when you get right down to it. They tried to spiff it up some, but it's boring. Even a Fiat 500 is more interesting (more likely to trigger a reaction, good or bad).
Cars have lost their art in favor of homogeny from a profit and economy/performance standpoint.. the art is largely gone. Same as in pop art (music, TV, etc) which is more formulaic than groundbreaking or adventurous (with notable exceptions).
