The cost to own America's own 638-horsepower supercar just got more expensive. GM recently released prices of all Corvette models to dealers and the 2010 Corvette will now start at $107,830. Add the required $1,700 gas guzzler tax for the Corvette ZR1 and the new out the door price increases to $109,530, an increase of $2,910 over the 2009's MSRP + gas tax of $106,620.
