No, you generally cannot buy a new or from a licensed dealership on a Sunday in Washington State. This is due to a long-standing state law that prohibits vehicle dealers from being open for the primary purpose of selling vehicles on Sundays. The law is designed to provide a uniform day of rest for the automotive industry. However, you can still perform other activities related to the car-buying process, and there are exceptions for private-party sales.
The restriction applies to the finalization of the sale, including signing the purchase contract. Dealerships are permitted to be open on Sundays for service, parts, and maintenance. You can visit a dealership to look at cars, take a test drive (if staff is available for non-sales purposes), or discuss financing, but you will not be able to complete the purchase transaction until another day of the week.
If you are set on buying from a private individual (a person-to-person sale through platforms like Craigslist or Facebook Marketplace), Sunday sales are perfectly legal. There are no restrictions on private party transactions. For dealership purchases, your best bet is to plan your car-buying activities for Monday through Saturday. Many dealers have extended hours on Saturdays to accommodate weekend shoppers.

Nope, Sunday is a no-go for signing the papers at any dealership here. It's a state law. I learned that the hard way when I tried to drive off the lot with my new SUV on a Sunday afternoon. The salesman was super nice about it, but he said his hands were tied. We did everything else—test drive, haggling, even got the financing approved. I just had to come back first thing Monday morning to make it official. It's a bit of an odd rule, but you just have to plan around it.

It's not allowed. Washington has what's called a "blue law" specifically for car dealerships. They can't be open to sell vehicles on Sundays. This means you can't complete the financial transaction or take official delivery. You can absolutely use Sunday as a day to do your research on the lot without the same weekend crowds. Just know that if you find "the one," you'll have to wait until Monday to make it yours.

Think of it this way: in Washington, dealerships are closed for on Sunday, but open for everything else. It’s actually a pretty good strategy to go on a Sunday. You can check out the inventory in peace, sit in the cars, and maybe even chat with a service advisor. There's zero sales pressure because they can't sell you anything. It’s the most relaxed car-browsing experience you'll get. Then, you're all prepared to negotiate when they open for sales on Monday.

Correct, the sale itself cannot happen on a Sunday. The law is very specific to the act of selling. This is why you might see dealership service bays open and a few staff around, but the finance office will be closed. Your only option for an immediate Sunday purchase is through a private seller. For a dealership, use Sunday for your research and be ready to act quickly once the week starts. Many buyers find this approach less stressful.
