In Delaware we have the Auto Theft Unit, which is run by the State Police. They hold it once a month at the DMV and check "questionable" vehicles to check if they are stolen or if the VIN plate is damaged, error on the title, ect. That's where most people take it first when they want to title a vehicle, but not register/tag it yet. No matter what you have here, in order to title it in your name you must take it through inspection first. Even if it's just a frame. And you only have 30 days from time of sale to do it. I got all messed up because of a boat trailer, was 60 days late, and had to pay a daily fine.
I don't understand why people just don't get a title. Ya some states don't require them, but if you want to sell it a title really helps. A friend had a bike from another state, sat on it as an "investment" and never got it titled. Year later no one wanted it 'cuz it had no title. He could have spent a little money and got a title, but instead sold it for half of what he paid for it. I don't care what it is, I've been screwed before, and won't buy anything without a title.
