my grandad has a 95 mustang gt and he's talking about handing it down to me. it's black with a black interior and a black convertible top 5.0 5 speed chrome cobra rims and a couple of minor mods. he's going to give it to me since he'll still have his roush. my question is do do i leave the interior alone. i live in GA and the summers get really hot esp. w/ black leather. also how would you mod it? what would it take to beat the roush?
