Do you drive, have you ever, a Honda Civic?
I have not! I have heard though, that Honda Civic's are great Japanese made cars!
Aren't they used as street racer cars?  You know, all juiced up with nitro and whatever?
I think they are very often used as street racer cars. The Honda Civic Type R has the highest performance of any Honda Civics made by the Honda Motor Company of Japan. Maybe they use those for street racing? 
Weren't there some in the original The Fast and the Furious?
