Pdr is an option so if you want it you need to find one with it. All zl1 cars have the npp exhaust with the valve that changes noise level based on mode and throttle input. All zl1s have mag ride unless you get a zl1 1le. Can’t help you with the automatic as I have never owned a performance car with an automatic. You will be perfectly fine with those mods. Do you plan on taking the car to a track ( road course track) if you do and you drive extremely hard you may want to consider a manual as the automatic cars can overheat due to the extra cooling involved with the automatic. Not a big concern if you don’t drive it at almost a professional race car driver level. On a 60-70 degree f day you can drive it hard and you won’t have an issue but on a 90 degree f day you will if driven extremely hard even without the mods (stock)
