STUNNING !!! 2013 Chevrolet Corvette LS7 427 (525HP) Convertible 60 Year ANIVERSARY COLLECTOR EDITION... During the C6 Corvette run, Chevy engineers were worried that the aluminum chassis rails used on the Z06 were not stiff enough for a convertible so, in 2013, they decided to use a steel chassis under the convertible and named it 427 Corvette instead of Z06. In the end, the 427 Corvette Convertible is essentially a Z06 with a steel chassis...Hence, all that Z06 equipment , engine, transmission, steering, brakes, etc., makes the 427 drive just like the Z06. Chevy refuses to call the 427 droptop a Z06 because the engineers insist the Z06 was designed to be a coupe and that it would not take kindly to having it's magnesium-reinforced roof panel simply removed. Therefore, the steel frame for structural support. This is a must see, must have, car for the right collector.
