OK, have to disagree there, Buick styling is very different from current Cadillac styling on the inside. There is no mistaking one for the other. And I'm a Caddy fan who currently drives a Buick if that means anything.You’re a big Cadillac fan. Most people are not, and you are in the minority.
This interior is far from unique and can be easily mistaken for a Buick with badging covered. Your bias is showing.
