DMV will sort it out when you register the car. At the very least, you will thave to pay registration fees of circa $300 for CA. Expect to pay the sales/use tax on the car--most likely the difference between the Broward rate & the rate in the county you're now living in. e.g. San Diego County is 7.75%, so you'd pay an additional 1.75% of the purchase price (including mark-up, if any!!!)
I could--because your car will be brand new--be wrong. You may be expected to pay the full sales tax. CA typically expects full sales tax on cars first registered for use in CA. Check with some of the CA owners who've bought out of state. Do a search on M2 & NAM for "out of state purchase". You'll get more info.
History: There are "loopholes" in CA law--it used to be you (as a CA resident) could register the vehicle out of state, leave it there for 90 days & then bring it in without paying the additional sales/use tax. I think they've expanded that window to a year. This was done in an effort to cut down on false out ot state registrations. OR & AZ registarations are (or were) so much cheaper than CA registration, that it made financial sense to do register out of state, then slide into CA down the line. I think it was partly due to the reg fees, but mostly because sales tax was so much less out of state.
(Meanwhile, Monterey bound GP owners are all wincing at the thought of use tax.
