How do I receive a rightful refund for a used car?

"My fiancé and I are young and this is our first time buying a car. We got a loan from our bank and we jumped the gun with this lot/car choice. We are unsatisfied and we just want our money back so we can be on our way and go somewhere else" ...Despite what you may have been indoctrinated to believe, there are no "do overs" or "take backs" in the real world. That you are "young" and buying your first car, imposes on you the obligation to be MORE diligent than usual or secure the help of someone knowledgable in advance to assist you. The millenial strategy of "point and pout" by just doing things because you can and dealing with bad results later, such as when someone takes advantage of you, is simply useless in comparison to taking the time to make proper decisions in advance. This is especially true when you factor in the cost and expense of hiring lawyers to sort things out can exceed the amount in controversy. The old adage of " an ounce of prevention being worth a poundof cure" comes into play here..  The above stated, if you bought the car "as -is" that means when it drives off the lot and you signed the papers, its YOUR car and any repairs or problems are yours also. The exception to this is fraud or violation of Fla. Stat. 501.976, but thats a VERY expensive lawsuit to pursue and very high risk as fraud is a very hard standard to prove. Simply being "unsatisfied" is nowhere close to meeting that standard as you have to prove actual deception, and "we're young and didn't know better" does not meet that standard. Sadly, this will likely be an expensive learning lesson for both of you about being more discriminating and diligent in your financial affairs.
