Car buyers in Washington pay a 6.5% state sales tax and an average dealer documentation fee of about $199 on top of the negotiated vehicle price. Add title, registration, and any local county or city taxes, and that's the gap between the sticker price and your true out-the-door cost. Whether you're buying in Seattle, Spokane or Tacoma, knowing these numbers before you walk into the dealership lets you negotiate the total price — not the monthly payment — and spot any add-on fee that doesn't belong on the contract.
