Dealer Data Specifications

How to provide your dealer inventory data to CLASSIC.COM 

Thanks for your interest in including your listings on CLASSIC.COM! If you represent a dealer or broker that sells classic, exotic, or specialty cars, please fill out this form to express interest.

We require that all sources be available in English and provide listings with up-to-date, accurate, factual, public information, including but not limited to:

  • Year, Make, and Model
  • Title (if year, make and model not provided as separate fields)
  • VIN (or Chassis/Series if older than 1981)
  • Location at time of sale (City, State, Country, Zipcode/Postal Code)
  • Status: For Sale, Sold, Not Sold (or equivalent status)
  • Asking Price
  • Images (at least 5 per listing – including exterior and interior views)
  • Odometer
  • Text description


It is your responsibility to ensure that the data is updated and accurate – including the required fields of VIN for every listing and final sale price (or highest bid if applicable) for all listings provided post-auction.

We reserve the right to approve or deny any inclusion requests at our own discretion, and remove data sources and/or listings that lack transparency, are misleading, outdated, or used as "click bait" to attract leads for other vehicles or purposes.

Once you are an approved Partner, we typically receive data via data feed from one of our approved IMS Partners, or via Manual Upload. We can also provide custom connections. All data integration options are outlined below.

Which integration method is right for you?

CLASSIC.COM supports three ways to get your dealer inventory onto the platform:

  • IMS connection: The most popular method is to provide us a connection with your IMS (Inventory Management System) who can provide a data feed. Simply email your IMS contact and cc partnersupport@classic.com with your request. We'll handle it from there.

    We connect with over 100 different IMS systems, including:

    • SpeedDigital / Dealer Accelerate
    • AllAutoNetwork
    • vAuto
    • Homenet
    • DealerCenter
    • DealerCarSearch
    • AutoManager
    • and more! 

  • Manual Submission: If you do not have an IMS connection and want to upload your listings manually, we have a simple tool that guides you through the process.

  • Custom Connection: Some partners have a development team that can provide API access to your inventory feed directly. This type of custom setup is available, but may require a setup fee.

IMS Feed example

Feeds provided via IMS are typically provided by sending daily CSV files via FTP. All fields must follow specifications described in the Full Field Reference section below.
