This isn’t downvoted as I expected, so maybe I’m overreacting. I don’t find the setup clear enough to answer (mixing very different aspects of discovery and price-setting, switching from auction to very-low-volume assymetric-information transactions, confusing theory of incentive-compatibility and strategy-proofness with the practical annoyance of car salesman tactics). But maybe it’s just me—I look forward to your actual post that explains which aspects of things your idea addresses, and how.
