I have this car and got many stored away. They are not civics, since they were not imported untill 1973. They are called a Honda 600 coupe or sedan.They have 10 inch tires and have a 600cc engine.I can not wait for some money to come my way to get one back on the road. My coupe, went as fast as 98 mph.I drove a Honda 600 up a tall bridge with a passenger on one cylinder one time when i striped out the spark plug hole. Do not buy a Honda Express, unless you get it for $50.
