Owned automotive inventory

We are not a reseller. We own the pages.

Most independent supply is arbitrage — somebody else's audience, marked up. Every impression here runs on a domain we registered, a page we wrote, and a server we operate.

The network.

300+domains, one per Mercedes-Benz chassis
3,000+pages of editorial across the network
4display placements on every page, on every template
205Nielsen markets addressable by geo at the edge

Network figures current as of August 2026. Placement and page counts are verified by direct fetch.

An enthusiast looking up a W124 is not an audience segment we bought. They arrived at a page about the exact car they own, and that intent is the product.

The network covers chassis from pre-war through current production, each with overview, history, specifications, buyer guides, specialists, market, recalls and registry.

The stack, stated plainly.

Open source by default is a policy here, not a preference. Every layer above is either open source or source-available and self-hosted, which means we can audit it and so can you.

Direct-sold gets first look.

How it works

First look, then fill

A booked advertiser renders before the auction runs. Programmatic fills what direct-sold does not, on the same four placements. No extra page zones, no bloat.

What is sold

Chassis by market

Exclusivity is per chassis, per market. A specialist can own W124 in their metro without buying the network, which is why there are tens of thousands of sellable positions rather than 285.

Who buys it

Independent specialists

Restoration shops, parts suppliers and marques who want the person already reading about the car they service.

About

Audacities Advertising operates the advertising side of the Proselyte Holdings portfolio — the network, the ad stack, and the direct-sold desk that sits on top of it.

The network is SternBaureihe, a domain per Mercedes-Benz chassis, built and maintained in house rather than acquired.

What we will not claim. Traffic figures are given as measured, never projected. Certification status is stated as it stands. We had an internal audit strike three overstated claims from a supply brief before it was sent, and that is the standard.

All commercial agreements are with Proselyte Holdings, Inc. Henderson, Nevada; correspondence to West Palm Beach, Florida.

Talk to us.

Buyers, supply partners and exchanges all reach the same desk. Tell us which you are and what you need to see.

Nothing here is an insertion order. Inventory, floors and terms are agreed in writing.
