Don't go turning my thread into a flame war Sheep.
Everyone has their opinions. I've had Honda's in the past, but I fell in love with the 5.0 back in 86 when my mom bought one and I've loved Mustangs ever since.
You can pull up TONS of examples of American cars whoopin up on rice rockets and vice versa. I personally can't stand the stupid "Rice Boy" subculture that seems to go along with tricked out Japanese cars. That said, I have seen many Japanese cars that were truly bad-***. I remember seeing a Honda Civic keep up with a Viper in a rolling start freeway race. But American cars are my preference.
And saying that American cars can't handle is a crock. My 95 GT with subframes, tubular K-member and control arms, yada, yada, yada, will smoke most cars on the road on the twisties. And the new Mustang is even better. Add a Griggs suspension to a new Mustang and you've got a SERIOUS corner carver!
It's just a question of what you're into.
