In addition to traditional dealerships and the private used market, cars of all makes and models are frequently sold in auctions. The car auction market was valued at around $3.32 billion in 2023, representing a growing avenue for buying and selling vehicles.

There are two types of car auctions: public ones, which anyone can attend, and private ones, which require a license. Discover the differences between these auctions, what types of cars each sells, and the licensing requirements for participating in private events.
Car auctions fall into two broad categories: public and license-only. Each type determines who can attend and focuses on different categories of vehicles.
Public auctions are accessible to anyone; as long as attendees have enough money, they can bid on and purchase as many vehicles as they need. A public auction offers a wide range of older, high-mileage vehicles of similar quality to the average used car.
Some public auctions are managed by government entities and police departments selling retired fleet vehicles or seized property. Others specialize in salvage titles, allowing experienced car buyers to find low-cost project vehicles, provided they are ready to repair or restore the cars themselves.
Many public car auctions also offer online bidding, allowing individuals to purchase vehicles without being physically present on the lot or the auction site.
Some car auctions are accessible only to individuals with a specific license. They generally sell newer, lower-mileage vehicles from select sources. Depending on the entity holding a license-only auction, the vehicles on auction may come from:
Although commonly referred to as an auction license, the permit needed to attend a license-only auction is a vehicle dealer’s license. It is not specific to car auctions; it allows individuals to buy and sell new and used vehicles as a profession.
Federal law considers anyone who is “engaged in the business” of buying and selling cars if it is their primary source of income. Most people do not need this license to buy and sell vehicles for their collections as long as it isn’t their main occupation or source of income.
However, those who make a living off trading vehicles or wish to attend a license-only auction (also referred to as a dealer or dealer-only auction) must obtain a dealer’s license.
Each state’s DMV or equivalent agency handles vehicle dealer licenses. Some states may have multiple licenses, such as those specific to motorcycles, used vehicles, or wholesaling.
While the exact requirements and procedures to follow vary by state, most have similar basic requirements:
Applicants should visit their DMV’s website for the most up-to-date information on all licensing requirements.
A vehicle dealer’s license can grant access to more auctions and allow buyers to find a wider variety of vehicles. However, used car buyers should know the potential challenges in obtaining and maintaining this license.
While a dealer’s license provides buyers access to auctions and unique used vehicles that are unavailable to the public, its primary purpose is a business license. Individuals interested in attending dealer-only auctions shouldn’t apply for a dealer’s license unless they plan to start an auto buying and selling business.
