I recently ordered a model S (yet to built inventory car) (blue exterior white interior with EAP and Premium package). Only reason I m getting Premium package is for the UHFS. I live in northern alabama and heated steering, heated rear seats is something I can live with. But now there are about inventory cars with blue exterior and cream interior without PUP that caught my eye. All cars do not have transportation charge for my location. So my question is spending extra $5k is really worth it for PUP? Is there any other mods I can do to improve sounds (such as installing NVX boost sub and light harmonic speakers)? I couldn't find any experiance installer with teslas for NVX in Alabama or Massachusetts that kind of worries me giving my brand new car to a audio shop so they can remove panels and install the sound system what if something goes wrong and what if panels starts to vibrate? What are your recommendations and any experienced installers that I can get recommended in north east or alabama area?
