If you're on old car guy, you'll know he's purposely exaggerating for effect and pulling many issues across the car's time and placing them all together. Many of us have faced the issues he's describing at different times with older cars and so we can relate and nod our heads. The fact that he's a professor of automotive engineering, and has pictures of the drivetrain out of the car and a welder in hand doing bodywork shows that he doesn't actually drive a neglected 914 like a foolish teenager.
I've bought many an abused old car, including a 951 a couple years ago that had many similar issues. So I know what he's talking about. That doesn't mean I didn't fix the car and have it running smoothly now.
