What's different about buying in Washington

Washington's combined rates are steep — 6.5% state + 0.3% motor vehicle tax + local, putting Seattle buyers over 10% — but the $200 doc fee cap and full trade-in credit claw some of that back. On a decent trade, the credit is worth over $1,000 in tax savings, so trading in usually beats selling private here.

Trade-in mathYour trade-in's value is deducted from the purchase price before tax is calculated. A $15,000 trade saves you $1,020 in tax here — which usually makes trading in beat a private sale once you factor in the hassle.
