Ford has priced the Shelby GT500 at $42,975 in coupe guise and $47,800 in convertible form (prices include destination charges and a gas guzzler tax). In exchange for that handsome sum, new owners of the Shelby will also enjoy power mirrors, a 500-watt sound system with an MP3 player and six-disc CD changer, front and front-side airbags, as well as power door locks and windows. In other words, while the interior amenities are nice, buyers are obviously paying for the powertrain and not a slew of upgrades such as navigation systems or ventilated seats.
