Yes you can. Demo is not a registered car
A few purchasing tips from a fellow EV/taycan guy: (1) Let the rep know as soon as you sit down at his desk to go over your configuration that the $7,500 Federal Tax credit is your money, he can't touch it, and you demand the same discount off MSRP that his dealership is offering on ICE Porsches (which is really easy to determine by googling customer reviews for that particular dealer); (2) unless you are emotionally needy, be sure and advise the sales rep that you would prefer to purchase a vehicle from him (locally) but that you are just fine ordering it from a stranger/out of state dealer who sells more Porsches and has more allocations/clout than the guy with whom you are negotiating; (3) if you are happy with off-the-shelf, i.e. not too particular about options, then get online and work the phones -- it doesn't cost sh!t to ship a car compared to the money you can save; (4) do not appear to be overanxious (it is really hard not to chomp at the bit when you see and touch the car at the dealership, but you can not project anything but calm and patience); (5) finally, recognize that the dealer absolutely has the best EV on the road (for now) and that gives him a slight advantage. Do not state that you are considering a Tesla Model S -- Taycans and Teslas are not an apples to apples thing and the dealer knows that you know this. The better approach is to advise that you are ready to purchase now, but if you can't get what you want for the right price for 5 or 6 months from Porsche, you will likely wait to see how the MB EQE (with a very comparable base price to the Taycan) looks when it is unveiled in Sept. And then mention that based on the EQS German configurator, the EQE will likely have a much more refined interior and lots of tech as standard equipment. (Porsche dealers know that the EQE will give them fits and if they are smart they will fill up their order books before the real competition hits the market). Good luck!
None of the Bay Area dealers were able to hold onto their inventory for long. Often I'd call about a car and it was already sold almost immediately after it hit the website. This probably happened 4-5 times. I was agnostic about color, but the specs I wanted were probably highly sought after. I also think a lot of people are running over on their leases, and several Tesla Model S buyers are still waiting for their cars, so the local demand and willingness to pay is through the roof. Even highly spec'd Taycan 4S cars with $140-145K in options are selling very quickly.
Speaking of CA sales tax, being in southern California, I'm registering my next car at a friends house in Moorpark, Ventura County.
Are you serious! It’s really worth doing this to save X.
To save 3% just by putting a different address that requires no extra work? For me it is
