On December 3, 2007, Chrysler started taking deposits for the third-generation Dodge Challenger which debuted on February 6, 2008 simultaneously at the Chicago Auto Show^[9] and Philadelphia International Auto Show. Listing at US$40,095, the new version is a 2-door coupe which shares common design elements with the first generation Challenger, despite being significantly longer and taller. The chassis is a modified (shortened wheelbase) version of the LX platform that underpins the 2006-Current Dodge Charger, 2005-2008 Dodge Magnum, and the 2005-Current Chrysler 300. The LX platform was adapted from the Mercedes E Class, reflecting the German company's ownership of Chrysler at the time and quest for economies of scale. All (7119) 2008 models were SRT8s and equipped with the 6.1 L (370 cu in) Hemi and a 5-speed AutoStick automatic transmission. The entire 2008 US run of 6,400 cars were pre-sold (many of which for above MSRP), and production commenced on May 8, 2008; Chrysler Canada offered a further 670+ SRTs uniquely badged as the Challenger 500 (paying homage to Charger and Coronet 500s) all of which were shipped to Canadian Dodge dealers. Chrysler of Mexico is offering only 100 of this car for that country with a 6.1 liter V8 and 425 brake horsepower (317 kW) (SAE); the version is SRT8. Chrysler auctioned off two 2008 SRT8 for charity with car #1 going for $400,000.00 to benefit the notMYkid non-profit organization, and a "B5" Blue #43 car fetching a winning bid of $228,143.43 with the proceeds going to Victory Junction Gang Camp.^[10]
