We haven't sold any vehicles here since 2016. I retired at age 35 and started a second career in vehicle repair and sales. Sold my repair business in 2011 and did quite well.
Basically, I lined my pockets from 1998 to 2016 selling cars online. I used to do no reserve auctions and most of the time did quite well. However, if the car was not going to make a profit, I would pull the listing.
After that, I listed with a reserve. When the most common question became "what's the reserve" like a parrot repeating itself, we did a simple buy it now format.
No one is willing to lose money on cars. I'd prefer to make profits. However, we've stopped selling on eBay and found other avenues where the sales are easier.
The reason that no one will offer a no reserve car is that everyone hunkers down and tries to bid at the last minute. You might do well and you might lose your panties. If you think it is such a good idea, get licensed as a dealer, start all of your cars at a dollar and show us all how its done.
