No to argue the point, but to see how I would read it.
ESP would be all american inline 6 cylinders, all V6 sedans, and V8 sedans and pickups NOC.
notice I would not see it as all american inline 6 cylinders, all american V6, all american v8 sedans and pickups NOC.
DSP would come before ESP so,
DSP catch all of All V6 and Turbo sedans under 3.0L would come first.
