I'd hoped there'd be a glut of used C6 Vettes on the market since the 2020 and 2021 Vettes are being produced
not so far, but I'm a patient man
With so little international/exotic travel, people with disposable income, are looking way closer to home, for their spending desires. Luxury and recreation products and activities that lend themselves to personal use, or isolated family use, are in high demand.
So boats, RVs, domestic vacation properties, "fun" vehicles, are all selling quickly, and for high dollars. For similar reasons, exercise and outdoor equipment are in short supply as well.
As badge points out, in another 1-2 years, a lot of those people are going be selling, because they either realize they didn't use it as much as they planned, or they can now spend their recreational dollars elsewhere, on foreign travel or whatever. So I'd anticipate prices to fall dramatically on luxury items at that point, especially on the secondary market.
