Yeah, I sensed you were going through a rough spot vehicle-wise. Like, it was going to stay on vacation longer than you.
Another reason why we now opt to fly and drive (rent) someone else's vehicle on our January FL trip. If it breaks down, our inconvenience is only how long we have to sit for someone to bring us another one. We had a minor problem last year, a leaky tire, and after calling an 800#, all we had to do is have it fixed. We got reimbursed.
I stuck my nose in this thread because we useta operate a driveaway business, so we useta carry a 10-pack of
trip permits.
A trip permit is for a one-way, direct trip, so you might need something more than that, like a 30-day permit if FL offers one. Sometimes we would use trip permits for a little more than a trip, but car dealers in every state I am familiar with have the 30-day permits, and put them on cars to give you 30 days to get it registered.
From what it said on the FL DMV it sounds like they will want you to settle up on sales tax, probably the amount you would owe in OH, show proof of insurance, and then put a temporary permit on it until you get home to register it in OH. You may have a sticky wicket on sales tax, unless you have actually disposed on your dearly departed vehicle. If you have not, you can't figure a trade difference, to minimize sales tax.
FL appears to have a $100 flat fee for first-time registration of a vehicle, another reason not to register it in FL (as if not being a resident wouldn't be enough of a reason).
Can you register in OH via the Internet, and transfer your old tags to the new vehicle. We can do vehicle stuff on the Internet now, and I have not had to stand in a DMV line for the last two years.
I assume you wisely took the tags off your old one, right? You wouldn't want the cops knocking on your door because
your vehicle was involved in a crime! (That happened to me once. They came looking for me because of all of the traffic fines against
my car. It was in a state where the plates went with the car, and the new owner never registered it.)
