I used to have a 1969 Buick Riviera with a 430 4-barrel carb engine. It was very heaavy and not so fast as the hp rating would make you think. So much was operated on engine vacuum. Especially the headlights folded down with vacuum hoses. And the hoses were always cracking or leaking and the headlights would only partially fold down so they were shining up in the air. My friends called my car “the raccoon hunter”.
My wife had a 95 Riviera and I rarely drove it. Now she drives a 2010 Buick LaCrosse and it has all kind of pretty buttons on the steering wheel and the owners manual is 315 pages...
