You are correct. It only started in 2013. The change was intended to give a cleaner, less congested branding appearance and was communicated through a GM Marketing Administrative message. I haven't been on GM lot in a while.

Every car you mentioned is manufactured in Europe (including the Regal). They do things differently than vehicles built in the US.

and none of these carry the Buick nameplate anymore; just the tricolor logo.

Nissan Titan's sales figures for August 2019 were only 2.5% of the total number of pickups sold in the US. Most of that figure is repeating customers. Any new bell or whistle (the other guys have) should be on the Titan including GMC's top of the line tailgate.

Is any Buick being manufactured in America anymore?

The 2020 Nissan Titan reminds me of the mid-1970s Volvo 240. A very safe vehicle with a lot of standard equipment and very few optional upgrades unless you move up a trim level. It does not have enough cameras or other driver safety equipment.

Has anyone noticed the dash of the Madza6? It pays homage to a 1964 Ford Galaxie 500. Both have almost the same clean lines.
