Am I being a snob? (Or just uninformed)

Really, is this a luxury sedan? Cadillac is not the first brand that springs to mind when I think of a luxury sedan. Maybe, Mercedes Benz, or BMW, or even Lexus. But not Cadillac.

Now, I admit, I'm not a car person, and I have no idea if Cadillac's quality has improved by leaps and bounds in recent years.  Perhaps the quality has improved, but I still think that this is a bit of stretch for most consumers.
