want to sell it? I bought an older car from a lady a couple months ago and haven't had the chance to get the title switched.. She wrote "Bill of sale" to me and everything. The transmission started slipping so I stopped driving it for a while. Someone is now interested in buying the car but I don't know what I'm supposed to do if I never put the car title under my name. Do I just write another bill of sale to the new guy? I'm in Washington STATE by the way.
