Not a good experience and this is why it's always best to get some kind of warranty, even if it is for a couple of weeks from the garages that sell these cars, or to go there and thoroughly check out the car and its history. These cars, specially if they've been sitting for a long time, and not cared for through trickle chargers, etc can be a pain to get back to life once dead. Call the guy who sold it to you in Florida and complain.
