See GT500. Entirely built by Ford. Originally was supposed to be 2-3 year run, now is continued through 2014 or 15 at least. The 2012 GT500 will have an aluminum block from the factory. Way too many people are still "Wow..a SHELBY!" Even my certificate from Ford says that it is a "limited edition"...Uh huh...for how many decades?
I predict that the Raptors will outlive the Lightnings. The Raptor even has a race version out. The Boss is back (with race versions), we have SVT's everywhere now it seems and all I have to say is "Excellent!" Beta pics show a new Bronco coming out in the near future that is similar to the Raptor. I think it will happen. The SVT vehicles are winning races. That attracts fans which means more sales.
GT500 got the aluminum block for model year 2011.
