Contact the State Attorney's Office. You may want to send a letter to the SAO that includes copies of your bills. Your boyfriend may be required to pay restitution as a part of his sentence. If no restitution you may be able to sue him in civil court.
I am not sure why they didn't charge him with Grand Theft Auto which is a third degree felony. You may want to contact the Detective handling the case to find out the answer. I hope this is helpful.
Without reviewing all the facts and evidence, it is not possible to give a proper opinion regarding the liklihood of sucess of your case.
I agree with the other comments. You would likely need to contact the State Attorney's Office to question about a Grand Theft charge.
If he committed actual physical damage to your car that exceeded $1,000.00 then the State may be able to charge him with Felony Criminal Mischief.
Fla. Stat. sec. 806.13(3):
(3) If the damage is $1,000 or greater, or if there is interruption or impairment of a business operation or public communication, transportation, supply of water, gas or power, or other public service which costs $1,000 or more in labor and supplies to restore, it is a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.
Your ex-boyfriend should be charged with Grand Theft, a 3rd Degree felony, plain and simple. The discussion of how long the vehicle was missing ( 14 days??) is of no relevance whatsoever. Any taking of the property of another, regardless of the duration, is a theft. In addition, since he thereafter used the vehicle in a transaction with his drug dealer, he could also be charged with Dealing in Stolen Property, a 2nd Degree Felony which is punishable by up to 15 years.
If there's nothing more to the story, this decision by the prosecutor smells bad. Sounds like a quick resolution by taking the path of least resistance by the state attorney. I worked as a state attorney for 15 years. If you are not satisfied with the discussed disposition, you need to speak with the division chief's supervisor.
