neither, not an import tuner guy, im an american made V8 muscle guy rather its a car or truck, but the mustang GT is to weak and over rated, only mustangs worth buying for performance is anything above a GT as in Saleen, Roush, Cobra, Shelby GT500 and Super Snack, i'd rather have the 2010 Chevy Camaro SS, the SS has over 400 HP from the factory, the 2010 mustang GT only has a little over 300 HP which sadly for Ford thats the same as the 2010 Camaro V6, i know its not all about HP but still sad that the V8 GT mustang has the same HP as the V6 Camaro
so from what i've said i'd pick the new 2010 Chevy Camaro SS BUT from the 2 you asked i'll have to say the mustang but i'd have to mod it up
