Here's the ad. Not much change from recent years. But none of the dumbshits in the ad can recognize that big Buick emblem.
Similar to what they are currently doing with Opel in Germany where they have celebrities drive a new Opel and marvel at it "I can't believe I'm driving one of their cars!", "An Opel? You're joking!" or "I didn't even know they still made cars!" They are trying to resurrect a brand image and I suppose that - much like Opel - Buick went out of fashion as a car brand quite a while ago in the US.
I always liked how the name pronounced itself - "bjoo-ick", that was snappy. It's also the brand I would identify the most with typical oversized "US-Straßenkreuzer" (as we call them here: "US-street-battleships"), no doubt due to that first formative encounter with one.
As for the new Buick breed, individualistic looking they are not, but then - contrary to what car magazines sometimes give you as an impression - the market of car buyers with an individualistic taste is limited. Most people want reliability and something that is technologically somewhere between state of the art and affordable.
Speaking of Opels: The grill of that Skylark Convertible just yells "Opel!" to me, it could have been on anyone of the larger Opel models of the time.
