I know of course the folks @ Tesla will have the final say but I'm curious what folks here think or have experienced. My car is 'confirmed' and in queue but is not in production and isn't supposed to start build for four more weeks. I've started to wonder about the UHF sound system and adding it. I know for 2500$ it may not be super worth it and for that reason if it was 3000 (with the 500 fee on top) then its not for sure. But since I'm looking to make my car more expensive which gives them more profit anyways what are folks thoughts on if I'll be stuck with the 500$ fee if I made the change? I could get it with the car in active production or even just days away as they line up parts and queue up but they are a month away which makes me feel like it really isn't a burden on them. What are folks success of post confirmation changes without a fee? Has anyone been able to do that before?
