Heh - actually they do these days. It's very similar, supply chain shortages mean that used car prices have boomed massively during the pandemic, not just GPU prices. In some cases people are selling cars for over 100% of what they paid for them. Certainly cars bought in the past 1-2 years ago have a fair chance of getting 80% back assuming they are in good condition, not mega miles added and you didn't overpay to begin with. The normal depreciation curve has flattened massively.
i bought a skoda octavia vrs 2016 in lockdown 1 for £14k. went back for my first service and he said do i want to sell it, he would get £19k for it now. i was half tempted, main dealer, but a newer one would be £34k ex demo lol. i declined.
