I see some one selling an expensive nissan rogue for only 1k claiming that he's leaving for FL this sunday?

There is no "what if" here. Its a scam.

The vehicle is probably stolen and the title is a fake reproduction. You'll pay him, get keys and a fake title, and when you go to the DMV to get registration they'll scan the VIN and see that its been reported stolen. If you're lucky they will take the car and return it to its rightful owner and you're just out the $1000 you paid the scammer, but you could be charged with possession of stolen goods.

If someone is legitimately in a hurry to sell because they're moving away very soon, they can trade it in at a legitimate dealership and get a check the same day for a lot more than $1000.

The elite is faking that they took the real vaccine; the real vaccine will cause spiritual and physical damage. When will the official churches start praying for the false prophet? Orthodox Christian three hand signs are different than Buddhist mudras. Ecumenism = 263 heresies; each heresy leads to hell. Orthodoxy = the only true faith; Roman Catholics tried one cup - one spoon ritual and got sick with Bubonic plague; if heresy enters Orthodox monastery then monks/nuns will get sick with flu/tuberculosis (for instance); Orthodox churches who closed for COVID or had disposable cups/spoons or dipped spoon into alcohol are no longer brides of Christ (now they serve Satan and honor Satan's new COVID religion). Don’t go into UFO to be “healed” by evil demons; demons never do good. SSN is written as a barcode/QRcode; then it's put into a chip; chip is put into vaccine; chipped people are influenced (by super computers) to receive grey plastic card World Passport with no name on it (but when they stretch their hands to get it, gov't clerk presses secret button to administer the unforgivable green 666 tattoo by isotope rays). If you reject mark of the beast (by hiding within a 10-15 people group according to saints Gabriel Urgebadze and Seraphim of Sarov), then your direct ancestors go to heaven (according to saint Vyacheslav Krasheninnikov from Ural). First vaccine shuts off your immune system; second vaccine gives you diseases; third vaccine puts your immune system back and it will start fighting the diseases and will cause death. Saint Paisios from Mount Athos said that the devil wants to deceive the rich with freemasonry, poor with communism, and believers with ecumenism. Elpidios Vagianakis said that there will be seven “mark of the beast” vaccines; reject all of them! Documents are from Satan; burn all the documents that you can find. Electronics will be used to track you. Even old broken unplugged 1970 TV set will show the evil flying antichrist using Tesla's ether. Don’t go into UFO to be “healed” by evil demons; demons never do good; always pray the Jesus prayer or to saints who help right away (like saint Vyacheslav Krasheninnikov according to whom if you reject mark of the beast, then your direct ancestors go to heaven); forgive me.

Sounds like a scam since a 2012 is easily worth $7,000

As the old saying goes; "if it sounds too good to be true, it most likely is".

Any legitimate seller could get far more by just making an immediate cash sale to a car dealer. 

So there’s no reason to virtually give it away.

Scams like this rely entirely upon fools who are easily parted from their money. 

But if you don’t believe that then I have some lovely Magic Beans I’d be happy to sell you, and I’ll include a free storage box. Just ignore the fact that it says “Heinz” on the outside; that’s just there to fool thieves and make them look like cheap baked beans.

It is a scam.  And you are about to fall for it, line, bait and sinker.

What "he says" is irrelevant. This is a common scam. What's the worst that could happen? You lose your money.

If something seems too good to be true, it usually is. Don't waste your time because, unless it has serious mechanical problems or the seller doesn't have legal title, any one of the companies like Carmax and Carvana would pay $3-4 grand for it within 48 hours.
