The reason I asked to delete this post was because it seemed to me like it could got out of hand.
I hope my English is good enough to make you guys understand.
If not, sorry.
I understood your story the first time, I think people were concerned once you edited your posts, as then the entire story was not as apparent.
It's an unfortunate situation, but I think you have already waited far too long, and at this point the seller is taking advantage of your trust. I would approach this situation in an escalating manner, that is, first contact him, impress upon him the urgency with which you require a refund, and tell him if he fails to provide you with your money back you're going to take legal action. Do not allow him to make any excuses, the time for that has long since past, he doesn't get a week, he gets 3 business days, maximum, in case he needs to transfer funds from another bank. Once these three business days have gone by, I would contact a lawyer who has experience handling contract disputes - have them review the notarized contract, and ensure the land referenced is actually owned by this other party. If it is, proceed to sue this person and obtain a judgment against them for the amount you're owed.
Going to the police is only going to give the seller warning you're starting some kind of legal action against him, allowing him to hide assets, or create excuses, and will not result in any real action, and will likely not result in you getting your cash back. Giving him an opportunity to pay you your money back, and telling him flat out the free ride is over, seems to be the least intensive solution - if this doesn't work, you will need to seek legal help. Doing nothing is not an option, waiting this long, when you paid him cash, is ridiculous. If this person is telling the truth, which I doubt, his wife has no problem with him putting their property in a contract, and his wife has no problem with him taking your cash, but will not let him sell an automobile? I don't know the seller's exact situation, but for many nsx owners, their wives or gf's would be the first to put their car in the autotrader, to make up for lost attention :tongue:
I wish you luck in this transaction, you have been more than patient with this seller, and now is the time for action.
