Ah but you see it's LISTED at that price, it hasn't sold as far as I can see. You can list a Ford Focus at $20M if you want, doesn't mean it's worth that and will sell for that.@Samus: That was 2017, prices skyrocketed since then:
This Porsche 911 GT1 Is A $12.3 Million Gold Mine
The Ultra-rare GT1 Strassenversion is worth a fortune and with good reason.carbuzz.com
The valuation by Hagerty does seem a little on the low side but I doubt it was anything to do with PD feeling generous. Everything else they've listed since then has been in line with real life, give or take.
