I did some searching on the net and found some old Buick slogans...
Buick. It's All Good.
Isn't it time for a real car?
Buick. The spirit of American style.
Wouldn't you really rather have a Buick?
When better cars are built, Buick will build them.
Today the discriminating family finds it absolutely necessary to own two or more motor cars.
I got a chuckle at the real car slogan... It was probably a Jab aimed @ Toyota and Datsun in the 70's.
