They had them. My best friend's dad had an Olds with a diesel. Floor it and it smoked like a semi!
Since Olds had it, I'm sure Buick did to. They were crap however, and I'm amazed one still runs today!
Reminds me how he was always on the losing side of things. He bought a diesel car when they have all but died out here. He also had a Beta VCR when they came out....
