I have no idea what taxes are or need to be included by law by the dealer at the point of sale in Arizona. I know that in my state (State of Confusion) only the sales tax of 6.3% is collected by the dealer. In a private party sale that tax is collected when the buyer registers the car. We also have personal property tax which would probably be in the vicinity of $1050 on an '08 vehicle, but it varies by the car’s value and the mil levy in the part of the county one lives in. You need to check with your local DMV or county appraiser’s office to see if the dealer is supposed to collct those taxes, of if you will pay additional taxes when you register the car. A title by itself here is $10. A tag by itself maxes out at about $30. It’s that personal property tax that gets us.
