@riviera74, @NINETY EIGHT REGENCY, @smk4565, @dwightlooi ~ ALL the above premises are erroneous.
>>"Can anybody tell me the difference between today's Cadillac from all other luxury makes?"<<
If you can answer how Audi/BMW/mercedes/lexus are different than all other luxury makes, you can answer the same for Cadillac.
>>"The sedans do need to stop trying to be German."<<
They're not; it was the Germans who became distinctly American, then eclipsed Cadillac in many instances. This was a clear targeting/copying, and they did a good job by the '90s, but prior to they weren't even on the same field.
>>"Not everyone agrees the V-series is what Cadillac needs, though. Cadillac super cars “answer a question the world wasn't asking,”"<<
Wow, an issue "not everyone" agrees on? We're still on Earth, correct? "Not everyone" agrees with anything you care to mention, especially within the automotive industry.
>>"I agree with Riviera that Cadillac needs identity."<<
It has as much as any other luxury brand, with a richer heritage.
>>"It is NOT that Cadillac doesn't have an identity. It is that its identity keeps changing!"<<
It really hasn't in the 2000s. Prior to that, it was a near non-stop bemoaning of how out of step Cadillac was in the luxury field. They adjusted their course heading and now people want them to go back.
Where people fall into their own wormhole is their erroneous idea that Cadillac MUST be a singular, black & white, hard-line "definition"; a one-mission brand. I struggle to think of a multi-model mainstream brand that does this. I guess one might say ferrari or Lamborghini, tho ferrari's low point in the '80s is hard to remedy with their before & after.
Is Cadillac where I personally would advocate they be? Not exactly, but my perspective is highly unique. But it's from the vantage point that I can see the Overall Picture that people have cried out for 'Cadillac to go back to being Cadillac' with no Earthly idea how to define that or what that means.
