Insight — The advertised price is rarely what you pay. Sales tax plus registration, title and doc fees commonly add 8–12% on top. Negotiate the doc fee where it isn't capped, and always agree on the out-the-door number, not the sticker.

Where these figures come from
State-specific figures are compiled from each state's Department of Revenue / Motor Vehicles (tax regime, rate, title and registration schedules), the state Department of Insurance and NAIC compilations (statutory minimum liability limits), and the Tax Foundation (sales-tax rates). Liability minimums are statutory and the most precise values here; registration and title fees are representative base amounts that vary by a vehicle's weight, value, age and county; doc-fee caps and EV fees reflect the latest 2025–26 published amounts. All figures are estimates for guidance, not quotes or legal advice — verify current amounts with the relevant state agency before you buy.
