Can anyone clarify the reason for this discrepancy? Please see both links. http://www.edmunds.com/new/2007/ford/shelbygt500/100751535/specs.html This first link is what everyone sas the GT500 actually produces. http://www.kbb.com/kb/ki.dll/kw.kc.ncs2?kbb.TX;686356;TX027&76543&&;;nc;&5&07FOD6_SCP;060702 This second link is what Kelley's Blue Book seems to think the GT500 produces. Does Kelley have old info or are they right?
