1962 Chevrolet Corvair Monza.
When I took Driver's Education in 1966 I only just squeaked past with the bare minimum to pass. What killed me was parallel parking. When I took the test to get my first license I got 100%. I attribute this to the fact that the Torrance, California test lot had big whip antennae to park between so you wouldn't hurt someone else's car. They were far enough apart to put a Cadillac into, so that little Monza had no trouble at all.
Almost fifty years later I still have trouble parallel parking.
