Honda joke (but true story)

My brother and I grew up doing a lot of the same things. Both of us
started driving at 16 and always loved cars. Both of us are very
similar sharing the same hobbies, IQ and skills. Actually the only
difference between us is the knowledge of cars. He actually knows how
to repair a cars, while the only thing I know is how to do fill it up
with gas. His knowledge of cars would almost qualify him as a
mechanic. So we were talking about how he became so smart in auto
repairs. Well it turns out the main difference between us is he
always bought American cars and I always bought Hondas.
