What are my Options with a Car I Owe Money on?

What are my Options with a Car I Owe Money on?
Please advise me on the best way to handle the following situation:

I bought a car in Florida not knowing a couple of months later I would be living in Germany for an undefinate amount of time (married a German and employed in Germany). Because I wasn’t sure of how long I would be here (employment reasons) I decided it would not be wise to get rid of the new car right away. It has been a year of me making payments and insurance payments on something that is sitting in my sisters garage. I am ready to eliminate the problem and realize I will be losing a good chunk of money. I realize I can’t sell the car privately because I don’t own it. I just sent the Power of Attorney to my sister to be able to sell my car. What are my options to end this whole ordeal with my car? No one seems to know and I can’t find any answers. I thought possibly of selling it back to the place I purchase it for. They will offer about half of what I owe so I am a bit reluctant. Please help.

Power of Attorney vs.

Power of Attorney vs. Proxy Letter
I would like to knwo what the difference is between these two terms. I am translating a document in which a person must submit a power of attorney or (I think) a proxy letter. The terms in the foregin language both seem to mean power of attorney. It would be helpful to know the difference so that I can apply this knowledge to my translation.

Thank you.

Best Regards

Foreign Individual Investor on SME in India
How a foreign investor who had invested on a S.M.E. in India, being swindled and cheated by an Indian Employee, can seek legal course to recover his investment from this employee ? This Employee had fallsified ”Power of Attorney”, ”Title Deeds of Porperties” and ”Sale Deeds of Land & Machineries”.
Does this foreign investor should first lodge a compliant with Indian Embassy in his country of residence ?, followed by another Case with Criminal and/or Civil Laws in India ?
Is it better to directly to file a Case in Supreme Court of India, same time file another Case in the State High Court, where the crime was committed by the subject Employee ?
