LOL, way back in the seventies, when the new Aston Martin V-8 came out, British auto mag. writers bitched it looked like AM was trying to copy the Mustang.
The Toyota Celica GT was a non-denied Japanese attempt to build a car based on the Mustangs looks.
Euros and Asians all brought out cars Pony Car size performers, but time moves on and Mustang is the sole survivor in the U.S. while overseas, the category is still fairly strong.
