Most of the time, Laura will collect the sales tax when you close on the truck. They will then cut a check and send it, along with the paperwork (MSO, bill of sale, power of attorney, etc...) to the tax collector/tag agency/DMV in your home city or state. I know in both FL and GA (where we have done transactions) it's not a big deal. They call you when the paperwork arrives. You go into the office, sign the title applications, pay any additional fees if owed, and walk out with your tag and registration. The title is issue by the state, and then sent to the lienholder if financed. (Unless you live in FL in which case the title is kept electronically in Tallahassee.)
Generally speaking, if the vehicle is financed, the bank requires the dealership to collect the sales tax. It protects the bank from getting a lien placed on the vehicle by the state.
Not a big deal....the $$$ saved over buying local still outweighs taking an hour out of your life to go to the tax collector.
