The plural is deliberate. There isn’t one aftermarket, there are several, operating on different platforms with different pricing conventions and different buyer pools. A site named for the plural is positioned as an overview rather than one more venue.
Seeing inventory and completed sales across venues in one place is something the industry still lacks, which makes aggregation the most useful reading.
The market underneath is genuine: brokers, marketplaces, escrow services, appraisers, and a body of sales data scattered across half a dozen sources that agree with each other about half the time.
The name equally suits a comparables service, an industry publication, a broker directory, or an education resource for new entrants.
Two words, plural, no hyphen, .com, and it’s how people in the business describe the business.
