With more time spent really getting the surface finish like glass with an epoxy coating something like that could easily fetch well over 15k in the right market. It just needs to be seen by the right crowd. My friend lived in Dubai for 6 years and flew me there to visit for 2 weeks and if that was on display in the mall by The Burj Khalifa it wouldn’t last 3 days before it got purchased. Just park it by the valet entrance with a silent auction sign and wait.
I never felt so broke in my life until I tried shopping there. The entire 3 story mall has polished granite flooring and there were at least 5 super cars in the valet parking every time I went there. I never saw so many crazy things in one place before.
It wouldn’t get much locally but given the right exposure there is no doubt in my mind it would fetch a solid price.
