I sold a SPENT '69 280SL on eBay for what I thought to be astronomical money ($6800).
No floor boards, trunk floor gone, quarters rusty, fenders rusty, rockers rusty, engine was there but had not run for decades, manual trans had neutral at least so I could roll it on a trailer. Car was dark red with shards of tan interior bits. It was an original A/C car and came with a hardtop though. Plus I had the title.
Nevertheless you can use that as an example.
