Buick GS 400 original vintage advertisement. GS 400 comes with
a 400 cubic inch, 4-barrel, 340 hp V8. If you like a responsive
car, we're talking your language. The springs and shocks are
heavy duty jobs. We also put in a stabilizer bar. The way it
handles is hard to describe. You have to experience it firsthand.
Wouldn't you really rather have a Buick?
