The countdown to the next-generation (C7) Corvette has officially begun, as tours of the Bowling Green Assembly Plant will be temporarily suspended beginning on September 14 to allow for plant retooling.

That’s the necessary first step towards building the 2014 Corvette, but Chevrolet wants you to remember that 2013 Corvettes are still available. One such model is collector’s-edition 2013 Corvette 427 Convertible, which takes the key components of the Corvette Z06 and bolts them into a convertible body.

Like the Corvette Z06, Corvette 427 is powered by a 7.0-liter (or 427 cubic-inch) hand-built LS7 V-8, rated at 505 horsepower and 470 pound-feet of torque. That’s enough to get the car from 0-60 in 3.8 seconds, ensuring that your freshly-washed hair is completely dry by the time you get to your office. Or the end of your street, depending upon your driving habits.

There’s a Z06-derived suspension, too, including GM’s superb Magnetic Ride Control dampers (developed by Delphi), ensuring that the ride quality lives up to owner expectations. Carbon fiber is used to save weight on the hood, fenders and floor panels, giving the 427 a curb weight of 3,355 pounds.

We’re not sure how many 427 Corvettes Chevrolet will build, but we doubt it will return for the 2014 model year. As with the original 427 Corvettes, rarity will ensure that the latest generation retains its value well; if you want one, now is the time to hit up your local Chevy dealer.
