The Automotive Knowledge Test:
You scored 84!
You probably think this test is a children's book. You can set rod bearings to the exact clearance that the manual calls for with no margin of error. You can probably identify any car driving down the street within seconds, and you swear your car has a personality all its own. Congrats and happy motoring!
Strangely enough, I don't really do any car work myself - but having a scientific background and a penchant for computer system diagnosis & repair definitely applies well to automobiles.
Take the test!
