3). Bill of Sale and Copy of Temporary Title (this should be part of your paperwork you receive from your dealer)
4). Sales Tax depends on the state you purchase from and whether or not they have a reciprocal agreement with CA DMV. Some states collect sales tax and some do not. This will show on your bill of sale, if your dealer collected it and should be calculated based upon your city/county of residence.
5). CA DMV Registration Form (REG 343 Form) -

6). Check to pay registration fees and any tax applicable.
DMV process, IF you have all your paperwork in order as indicated above: check in, they will confirm your paperwork, go outside and wait for them to inspect your VIN and mileage (they will ask for you to open the hood), they will give you another form confirming inspection, go back inside wait for a window to open, turn everything in and walk out with plates.
