My question involves a consumer law issue in the State of: Washington
...for what I understand to be appropriate for this section. Please direct me to a correct category if I'm mistaken.

Post for a friend who purchased a used car from a used car lot. He drove it for 3 months. At some point who took it to a shop for maintenance purposes. At the shop he was advised that his car's frame is corroded. He then took his car to a dealership if his car's brand to have them look at it and see if he can qualify for a buy-back because apparently these cars were recalled by the brand. When the dealership inspected the car, they urged him immediately stop driving it because it was unsafe to drive. He didn't qualify for the buy back program because the program expired before he even purchased the car. I wish i had pics to share, the corrosion is terrifying.

Now for the qiestion. Can he go back to the used lot and request money back? He purchased the car AS IS. Are there laws in place that dictate a car lot cannot sell cars that are unsafe to drive? Or is he out of his money?

Thank you for your help and time.
