"The 11 cars now available in September's Pennzoil car pack for Forza Motorsport 4 are all pretty ... slick. For 560 MS Points ($7) you'll get a couple of Vipers, an Alfa Romeo 33 Stradale and a '53 Corvette, just to name a few. The full list of the cars can be seen past the break.Players that picked up a season pass for the game will have to shell out money for this DLC pack, as the last add-on to be included in the pass launched in April. New Community Monthly Rivals Mode events, including one that features the Pennzoil-sponsored Vipers, accompany this new release.%Gallery-164406%2013 Viper #91 SRT Motorsport GTS-R   2013 Viper #93 SRT Motorsport GTS-R   1968 Alfa Romeo 33 Stradale   1960 Aston Martin DB4 GT Zagato   1958 Austin-Healey Sprite MKI   1953 Chevrolet Corvette   1965 MG MGB GT   1955 Mercedes-Benz 300 SLR   1967 Volkswagen Karmann Ghia   1983 GMC Vandura G-1500   2011 Citro&amp;euml;n DS4"^^<http://www.w3.org/2001/XMLSchema#string>
