Unlicensed Motor Vehicle/Powersports Vehicle Dealers and Salespersons:Unlicensed motor vehicle/powersports vehicle dealers, "Curbstoners", pose a threat to consumers for many reasons.

  • Curbstoners are more likely to roll back odometers, commit salvage fraud and/or not disclose material damage.
  • Curbstoners often do not put the title to the vehicle in their name, so that once the deal is done, there is no evidence that links the curbstoner to the sale.
  • Curbstoners do not have a principal place of business; they have a tendency to move around, thereby making it difficult or impossible for a consumer to locate the curbstoner after the sale if a problem occurs.
  • These unlicensed dealers are not remitting sales tax to the State and local jurisdictions thereby avoiding their legal responsibilities.


Licensed Motor vehicle/Powersports Vehicle Dealers and Salespersons are regulated by the Colorado Motor Vehicle Dealer Board, the Colorado Consumer Protection Act and by federal laws. Motor vehicle/powersports vehicle dealers are licensed for the protection of consumers.
