Does Florida have a right to cancel a contract to purchase a used car.?

If you are asking is there a cooling off period or buyers remise law in Florida on the purchase of a used car the answer is no. Once you sign the contract you are legally bound to that contract and it cannot be cancelled unless the seller agrees to that cancelation. The Buyers Remorse or Cooling Off Period laws do not apply to the sale of a new or used vehicle in any state.
