I understand that the cars are built for different purposes somewhat. But what are the distinctives that push a prospective buyer towards '13 Boss 302LS versus '13 GT 500? Weight? Suspension? Brakes? other? I'd appreciate Ron and others opinions. Assume stock configuration on each except for the SVT track package on the GT500. I'm beginning to look, but in no hurry. I've never owned a Mustang except my '64 1/2 289 in the mid 60's! Bert
