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 New Mexico, crossing state lines to dodge New Mexico's 4% sales tax usually doesn't work — you'll still owe New Mexico 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 New Mexico tax) before deciding.
