Allstate offers suspended vehicle coverage where you call them prior to using your vehicle and again when you are done letting them know no one died and no accidents happened. They only charge you for the actual use time involved plus a basic $12 a year or such.
I had my COE covered under that for awhile and it was dirt cheap. They may not offer it for someone who doesn't carry their main policy with them.
I also use Hagerty for my '53 and it is pretty darn inexpensive.
