The FBI is warning consumers of scammers who, they say, are on the prowl, looking to steal your tax refund.

One of the more popular scams: Fraudulent online car sales.

If it sounds too good to be true, it's likely a scam

It doesn't take long to find a potentially fraudulent car sale. KSAT-12's Courtney Friedman did some searching and found a 2006 Acura for $2,000 and a 2005 Acura TL for just over $1,000. They look like good deals, but the FBI said they're most likely scams.

"The price tag is extremely enticing for the consumer and in the end you're not going to get anything at all," FBI spokesperson Michelle Lee said.

Courtney found another car on OfferUp and when she clicked the seller's profile, she discovered the seller listed the same car more than 50 times all in different cities.

Thousands of people have fallen for these scams

According to the FBI, from May 2014 to December 2017, the FBI's Internet Crime Complaint Center (IC3) received 26,967 complaints for these types of fraudulent online car sales.

The agency said that amounts to more than $54 million dollars in adjusted losses.

"People have become more comfortable purchasing things online," Lee said. "With that comfort level, we have individuals that are maybe becoming a little more careless and not looking out for signs the sales could be scams."

Don't become a victim

Lee said consumers should make sure the photos match the description of the vehicle. And, if there's an urgency to complete the sale, beware.

"They provide reasons why they're selling an item at such a discount," Lee said. "You know, 'I just got a divorce, I'm having to liquidate my assets."

The FBI has a list of tactics employed by scammers on its website and lists divorce, deployment and death as reasons frequently used by scammers.

Lee also advises buyers to beware of sellers who want money wired or want payment in gift cards. Also, investigate whether the site you are buying from offers buyer protection. Sites such as Craigslist or OfferUp where the seller can advertise for free do not offer buyer protection.
