The facts you present sound pretty much like a case I handled a few years back. I sued the car seller successfully in Florida (he was somewhere out west). The Florida court had jurisdiction because it was an internet sale. Good luck!
If you think my response is the best response, it would help me if you would indicate that. Also, please note that my responses to question(s) are NOT legal advice from me to you because I am NOT your lawyer, you are NOT my client, and we do NOT currently have an attorney-client relationship. Thanks!
