Man Test Drives Used Car, Feels Something Off. Then He Runs VIN Through Google Gemini: 'Don't Get Scammed By Used Car Dealership'

A car can look perfect on paper, but it still matters how you feel about it when you’re behind the wheel.

This buyer says that if you feel even a bit off about it you should trust your instincts and follow up on it. It may save you money and time. 

Here’s one simple way he says you can vet a car you’re looking at.

What Was Wrong With The Car?

In a TikTok by content creator Porter (@porterehurd), he shares the experience of a test drive gone wrong.

"I went and test drove a car yesterday. It felt off," he says. "I didn't like how it drove. It should have been a nice car, it should have driven really well, but it didn't."

The spec sheet looked perfect, he said, but the fact that it didn’t drive well kept him up that night, turning the question over in his head.

"I just couldn't figure out why it drove like that and why I didn't like it,” he said.

So he looked up the VIN. A couple of hits came back from auction history websites, but they were paywalled. He wasn't willing to pay to find out, and he'd already decided he didn't like the car enough to pursue it further. Then he noticed the AI tab on his Google search results.

"AI gave me a full readout of how it was $30,000 bought at auction with noted front-end damage," he says. "It was a salvage auction. And this car had then, in a couple months, been flipped, I guess, and was now being listed at almost $45,000."

He shared a screenshot of the AI summary which added even more detail explaining that it sold at a salvage and insurance auction in 2025 in Oregon, with a final bid of $30,250 and 26,853 miles on the odometer at the time. By May, about six months later, it had been repaired and relisted for sale at $46,491, with the odometer now reading 27,343 miles.

"In no way would you see this vehicle in person or online and think that it was a salvage title."

He’s now urging used car shoppers to look up the VIN and run it through Gemini or another AI tool before buying, because it may surface information that's sitting behind a paywall on traditional VIN-check sites. (It’s important to note that AI gets things wrong all the time and can hallucinate non-existent information in an effort to get you an answer. So don’t blindly trust what it says.)

"I feel like dealerships may not be aware that we can use this tool," he says. "This tool pulls more information than any Google search could."

"They might be hiding this from you,” he adds in the caption.

What Is A VIN, And What Can It Actually Tell You?

A VIN, or vehicle identification number, is a unique 17-character code assigned to every modern car the moment it's manufactured.

It functions almost like a social security number for the vehicle. It almost never changes, and it's used by dealerships, insurance companies, and government agencies to track everything that's happened to that specific car.

The VIN breaks down into segments. The first three characters identify the country of origin and manufacturer, the next several cover the model and engine type, and the last six digits are the car's unique serial number. 

The National Highway Traffic Safety Administration offers a free VIN decoder that can pull even more detail out of it. Checking a VIN there can reveal a car's accident history, salvage title status, recall history, and how frequently it's been serviced at a dealership.

You may also want to check for a less obvious red flag. If the VIN on the dashboard doesn't match the VIN on the door jamb or engine block, that's a serious warning sign of major damage history or even "chop shop" activity, and should be treated with extreme caution.

How To Check A Car's History 

A basic vehicle history report is a good start, but it doesn't always tell the whole story. Here are a few additional steps can fill in the gaps according to NerdWallet:

• Get a professional inspection. A pre-purchase inspection by an independent, third-party mechanic can catch hidden damage a standard report might miss. It typically costs several hundred dollars upfront, which can save thousands in repairs down the line.
• Run a free VIN check through the National Insurance Crime Bureau. The NICB’s VINCheck tool can show whether a car was ever reported stolen and never recovered, or declared a total loss by an insurer. NerdWallet cautions that not every "free VIN check" advertised online is legitimate, so it's best to stick to reputable sources like the NICB.
• Pull a title report through the National Motor Vehicle Title Information System. NMVTS consolidates data from state titling agencies, insurance carriers, and salvage yards into a report focused specifically on fraud indicators, like odometer discrepancies or hidden damage. It's often shorter and cheaper than a full vehicle history report.
• Contact the state department of motor vehicles directly. Title information can be incomplete or vary depending on the state, so checking DMV records where the car was registered can help verify or fill in gaps left by other reports.

Do Dealers Have To Disclose A Salvage Title?

According to a response published on Justia's Ask a Lawyer forum, in most states, a dealership is required to disclose if a vehicle was previously totaled or carries a salvage title.

The responsibility to ensure proper title designation falls on the dealer, not the buyer, especially when the vehicle came through an insurance auction where the salvage status would have been on record.

The attorney on the forum noted that selling a car without disclosing a known salvage history "could amount to fraud or deceptive business practices," and that affected buyers can file a complaint with their state's consumer protection office or pursue the matter in small claims or civil court.

“Trying To Not Get Scammed”

Porter’s advice was well-received.

“I’m car shopping right now. Thanks for the tip!!! Trying to not get scammed also,” one wrote.

“Wait such a good tip! That’s insane,” a second person said.

“Dealers know ppl can do this, they also know the average person isn’t gonna do it. That’s why if you find out this info but still really want the car, you use it to your advantage to negotiate a lower price,” another wrote.
