John, you're DMV is fucked up. Our Port St. Lucie office was too. And the Fort Pierce office still is. A bill of sale is all you need in FL. Call Tallahassee and report your DMV supervisor to them and they'll straighten him/her out.
We had to do it.
After the lady from the capital called and explained the law to them... I think now we could register an ATV if we wanted hahaha. They just see our business name and throw a plate to ya. It's pretty awesome. Way better than the headache it used to be. No last registered owner crap can legally get in the way of registering your ped.
Seriously a poopy piece of toilet paper with a hand written bill of sale is all you need. No matter what they say.
Again call Talahassee and tell them what is happening to you.
