Thank you for your patience
I ask about location since if the contract was negotiated in WA and the seller (dealership) is there? You have to sue there…and are limited by the laws in that state
If the dealership intentionally misled you on the car…that is, they lied to you about the condition, or they took steps to cover up a defect so you would not notice? That would be a basis to void the contract and sue for damages.
Also, if the sold you insurance and the insurance is not honoring the policy (the insurance is not honoring a claim that, according to the policy they should honor)? You could sue to void that policy and claim a refund.
You have a couple of options
One, you can use small claims court to reduce the cost.
Small claims is a true "peoples court". The formal rules of evidence and procedure do not apply. So you can represent yourself (no need to hire a lawyer).
The process is simple enough. You head to the county court (the county dealership pis located) and talk to the clerk of the court. They can get you the forms needed to start. You file the claim, serve a copy on the defendant and wait for your day in court.
In court, be prepared to tell the judge what happened, and bring in copies of any evidence that supports your case. IF there are witnesses who can testify about what happened? Have them come as well.
HOWEVER, you can only sue for up to $5K in small claims.
IF your goal is to sue for more? You will need to hire an attorney and let them file the case for you…but, of course, you will have to pay the attorney (which will reduce the money you ultimately receive)
