Charlie's '86 comes to mind.
This is a thread I started on Pennocks, a few years ago.

My question was "How can bad motor mounts affect the handling of a car whose suspension is otherwise in good condition?
The wheels are driven through CV axles. The position of the engine should have no bearing upon how the wheels are aligned."
The answer was that "Bad mounts will allow the engine to move around. That much weight, shifting around, especially in a turn, can cause the car to do funny things."
I bring this up, because I had to go to Tammy's mom's, yesterday for a family pow wow. Since I didn't get to come to the meeting, I decided to salvage the day, and drive the Fiero down to her place. I ended up breaking a motor/tranny mount. (Haven't got under the car, yet, to determine which one(s), but I could definitely feel the engine moving around. Not my first time at this rodeo.)
I noticed that the car seemed a bit less solidly planted than it normally does, so maybe there's something to this.
