While I respect your opinion on it, I don't quite agree on the interior. The ATS (and most current Caddys, for that matter) are not the cheap plastic junk inside anymore (the Catera and 1Gen CTS were probably the worst) that Cadillac used as recently as up to about 6-7 years ago.
Back to the new BMW 3/4 series, I hope to get a good look at them at the D.C. Auto Show in about two weeks. Among other things, one thing I'm going to check out is how their interiors compare with that of the ATS.
Nobody said they were "cheap plastic junk inside".
But the ATS interior is no match for current equivalent Mercedes or Lexus in terms of design/style, fit and finish, quality of materials used. Just look at the lame Caddy steering wheel for starters, any good interior designer knows the importance of getting that right. I already checked out/compared Caddy (ATS), BMW, Lexus, Mercedes interiors at SF car show in November and again will do same at SJ this week.
As I implied before, BMW (and Mercedes and Lexus) is smarter than using ATS as it's compact premium car benchmark. Cadillac is losing market share in a booming premium car market today, and ATS follows that trend unfortunately.
Let's see if the new 340 addresses some of the concerns and helps keep BMW in #1 spot...
