The new 1953-2012 Corvette Black Book continues its never-ending evolution. The 2011 data pages have been reworked to include production numbers for options and exterior colors. A new Addenda section adds dealer-installed options for 2009 through 2012s. Data for 2012 is included (no production quantities yet) and while it is another carryover year for the C6 series, Chevy engineers have made substantial improvements and changes which this new edition covers. For starters, seats have been reworked with bigger bolsters, especially in the shoulder area. To honor Chevrolet's 100th year, a new Centennial Edition is available across all Corvette models. A new exterior color, Carbon Flash, is required for the Centennial and all will have sinister black wheels and micro-suede seat inserts. Another new color, Carlisle Blue, is one year only and honors the big annual Corvette show in Carlisle, Pennsylvania.
