Almost right
There is a 2% title fee.
And if you live out of state, you still pay tax when you register the car.
I shop there to buy freom people I know and trust, not to save any money (well I don't complain if I also get a good deal)
This is true no matter where you buy the car.
e.g. Buy in PA, register in MD, pay MD tax
Buy in DE, register in MD pay MD tax
Buy in MD, register in De pay DE (2%)
