Sf-97
G.L. says one year but I sure wait that long.
I think that months or less would be good practice.
Once they say no, that's pretty much it.
It is nice to have the SF-97 showing the history of the vehicle for some collectors but almost mandatory in order to generate a title in most states.
Not title, no registration except for Alabama and perhaps one or two others.
I would want it for proof that it was never stolen.
You have to turn in the original, but I always make a really good color copy first.
