Is it a Porsche dealer or a generic dealer? I'd get a PPI done regardless if it comes with warranty.
Don't forget warranty doesn't cover any wearable items like brake disc/rotors, ball joints, bearings, clutch, etc etc etc...
Lower mileage or litronics, very tough call... let me ask you this: do you like your woman with pretty eyes?
I know I do!
I don't understand how people can live with the plastic window, but that's just me.
