The seller sounds like a regular person clearing out a car before a move, meeting you in a grocery store parking lot with a clean title and a story about why the price is so good. In a meaningful share of these deals, according to guidance from multiple state consumer protection offices, that “private seller” is actually a repeat operator running an unlicensed used car lot out of classified ads, a practice regulators call curbstoning. The term comes from cars parked curbside with handwritten for-sale signs, and it describes dealers who buy and resell vehicles by the dozen while posing as ordinary individuals so they never have to register, get bonded, or answer for what they sell. It works specifically because buyers assume private-party protections don’t apply the same way, and curbstoners are counting on exactly that assumption.
How the Con Actually Works
According to the Minnesota Attorney General’s office, a curbstoner is “an auto dealer who engages in a brisk business of buying and selling used vehicles in large quantities but doesn’t bother to get a proper license.” Minnesota law caps how many vehicles a person can sell in 12 months without a dealer license at five; go over that and you’re legally required to register as a dealer, carry a bond, and maintain a fixed place of business. Curbstoners route around all three requirements simply by never admitting they’re dealers. They post ads on classified sites, meet buyers in parking lots or on the street rather than at a residence, and often use a rotating cast of phone numbers and go-between “sellers” so no single name accumulates too long a paper trail with the DMV.
The San Diego City Attorney’s office, in a consumer advisory on curbstoning, describes the same pattern from the enforcement side: operators frequently source damaged or salvaged vehicles from auctions and salvage yards, then resell them without disclosing accident or title history, because a private seller in most states faces far fewer disclosure obligations than a licensed dealership does. That same office notes operating as an unlicensed dealer is a criminal misdemeanor in California, punishable by up to six months in jail and a $1,000 fine, with additional theft-by-false-pretense or forgery charges possible if paperwork gets altered.
Every Consumer Protection a Real Dealership Follows
Licensed dealerships operate under a stack of obligations curbstoners simply skip. Under the FTC’s Used Car Rule, referenced in Minnesota’s guidance, any seller moving six or more vehicles a year is legally a dealer and must post a window “Buyers Guide” disclosing whether the vehicle is sold with a warranty or strictly “as is.” Licensed dealers also have to carry a surety bond that gives defrauded buyers somewhere to file a claim, register a fixed business address regulators can inspect, and, in most states, run every vehicle through a title check before it changes hands. A curbstoner who never registers as a dealer in the first place has no bond for a buyer to claim against, no business address to return to when the car turns out to have a salvage title, and functionally no license for a state agency to revoke.
The Warning Signs Regulators Point To
Both agencies point buyers toward a similar set of tells. A seller’s name that doesn’t match the name on the title is the biggest one. So is the same phone number turning up across several unrelated “owner selling” listings, a refusal to meet at a home address, missing maintenance history, or a title that shows recent or repeated transfers rather than one long-term owner. A price that sits noticeably below comparable listings is also common, since curbstoners are usually clearing inventory fast rather than holding out for full value.
What to Do Before You Hand Over Cash
Run the VIN through a title history check before you meet, ask to see ID that matches the name on the title, and insist on completing the sale at the address listed on that title whenever possible. If a deal falls apart after the fact, both the Minnesota and California guidance point buyers toward filing a complaint with their state’s DMV dealer licensing unit rather than treating it as a private dispute, since regulators track repeat curbstoners across multiple complaints even when individual buyers never connect with each other.
Curbstoning survives by hiding inside a transaction type, the private used-car sale, that almost every American treats as inherently lower-risk than a dealership. Regulators keep publishing the same warning signs year after year for a reason: the private-seller label does most of the deceiving before a buyer ever lays eyes on the car.
