Stack manufacturer + state + lender programs whenever possible.
Sales tax is owed in the state where the vehicle is titled and registered, not where you buy it. So if you live in Washington, crossing state lines to dodge Washington's 6.50% sales tax usually doesn't work — you'll still owe Washington tax when you register at home. The exception is when neighboring inventory and dealer pricing are meaningfully better; in that case, compare full out-the-door totals (including Washington tax) before deciding.
