A few items he has wrong on the quiz.

1. what year were the first ZR-1s produced?  1970, if you want to be
technical.  If you refer to the C4 ZR-1, then 1989. There were 84 of them
produced and released to "special" people for testing and evaluation.

2. how many years were the ZR-1s produced? It depends on if you accept 1970
to 1972 and if you correct to 1989 to 1995.

3. what inspired the bow tie Corvette logo?  Right info, wrong car. This was
the logo that Durant found on a room in Paris that he then used for the
to-be-famous Chevrolet bow tie.  This occurred almost 40 years before
Corvette existed.

4. power steering?  Well, it wasn't 193, so you have the typo there like
Owen said.
