Mostly small stuff. The car came without a gas gauge. The turn signals didn't work. The tach was inaccurate and the
oil and water temp gauges were out. George also replaced the old front A arms with new adjustable ones so the car could be better aligned. The front ball joints had never been greased and were very worn and unsafe. etc etc. Basically no major design problems but the kind of stuff that will drive you crazy.
