Prinz,
Hey buddy, I'm just getting a chance to read your thread. I've purchased all of our vehicles out of state and never once paid more than one sales tax. Someone is definitely misinforming you. If you are getting your new car delivered, you don't have to worry about pre-registering it or anything because it's not going to be driven on the street so you don't need a temp. tag or anything until it gets to you. If you decide to pick the car up yourself and drive it home, all you have to do is go to a local DMV where you are buying the car from (with the seller) and they will pre-register everything for you and give you a temp. license plate to drive home on. It is your responsibility to register the car and pay all of your local taxes once you get home, and not before then. Other than a temp. tag fee, you shouldn't have to pay a penny until you get home.
