@mozartfan - my observation is that a well-run luxury brand emphasizing quality *never* runs a “sales event”, both to maintain long-term economics as well as value associated with the brand. They might offer discount on an older product line as it is being replaced ( @upscaleaudio might smack this assertion around)
If second-hand prices are falling, or dealers are selling “grey market” at a discount, then the maker cuts production and lives with lower revenue for a few years, but maintains pricing
The second-hand market is where price-sensitive buyers look for less expensive entry points
Rolex. Porsche. Hermes. Companies with brand value including quality and longevity, that sell massive volumes, but never discount
Appreciate the above contains generalizations in service of sharing an idea
