I've been a long term lurker of this forum (which is a wealth of information) and have been doing some research before purchasing a 2017 or later Model S P90 within the next 2 to 3 months. However I've noticed that used Model S prices outside of my state (CA) seem to be significantly less in different parts of the country which has made me a bit hesitant. With that said, if I purchase a Model S from outside of CA would I still be eligible for the CA rebate as long as the Model S has not been registered in CA? Would I still be eligible for the federal rebate?

i've purchased plenty of ice cars outside of CA so i'm familiar with the registration process but wasn't sure about my eligibility regarding the EV rebates. Lastly outside of what I mentioned above should there be anything else to be concerned about? I'm targeting low mileage Model S's (preferably below 12K miles) but any additional advice or insight the forum could provide would be appreciated!

Thanks
