Delaware inspects everything, any year. Even if it's just a frame you want to title, you have to literally walk it through inspection, they fail it and tell you what it needs and then you can get a title. If the bike does not have a 17 digit VIN stamped on the frame then you have to take it though ATU (Auto Theft Unit) so they can run the numbers. Which is the 3rd Thursday of the month.
My '81 had a clean Jersey title and passed inspection, but the VIN is not 17 digits, which started in '82, and I had to wait 3 weeks to take it through ATU.
Title services? Nope, they have a list of all of them and will check, then run the title number to see what is going on. My buddy had 3 bikes and a truck turned down.
Of course he went to another state and had a friend title it, then "sell" it back to him. But I'm not dealing with that crap.
My other friend lives in Maryland and they check the engine number to make sure it matches the frame. Uhm, '69 Honda, they didn't even come from the factory like that. He had a hell of a time.
States are getting really picky with titles.
