If, and only if, a car is registered as an antique in the state of Florida, you do not need a title, just a bill of sale. The DMV clerks don’t know this (in my case, the Lee County Tax Collector clerks). But it is true.
I found out about this when I brought in a 63 Alfa about four years ago. I shipped it in from Sweden and did all the customs and EPA forms myself. Came in through Jax Port. I had lots of paperwork in Swedish, and my Swedish friend Markus translated it, and there was no equivalent of a title, just a registration. I was in a pickle, I thought. I finally spoke with a helpful guy in the regional DMV office in Palmetto, FL. He was the inspector. What I had to do was to make an appointment with him on a certain day a month or so in advance. I met him at the main Lee County Tax Coll Office downtown. We met outside. Mostly he was verifying VINs on Canadian vehicles for folks who were moving here.
He verified the VIN on the car and that it matched the VIN on the Bill of Sale. Then he handed me a photocopy of the Florida legal code that said if a car was registered as an antique, then I did not need a title. I took that photocopy as well as the VIN verification form inside the office and registered the car and got a FL title. The clerk did not know the rules, so I had to show her the photocopy of the legal code, and she did her job.
This was three to four years ago, and things may have changed, but I don’t think so.
So there are helpful government employees out there and I was lucky enough to find one.
