No, or I sure wouldn’t be able to own one. Some parts are expensive, but what car doesn’t have pricey parts? The Model T, Maverick and old Beetle are long gone. There’s no such thing as an “easy to work on” modern car, at least not in this country. Find a retired Mercedes or other diesel mechanic and you’ll be in hog heaven.
Actually Chevrolet made a Diesel Chevette in the late 70's and early 80's which was a great car. Unfortunately GM ruined it's reputation so badly on the 350 engine modified for diesel in the same time period that the Diesel Chevette suffered an early death from the line.
