I really believe those buyers on the internet think that they have an innate shopping ability and even when they get ripped off they are afraid to admit it. We had a customer who bought a "reconditioned" truck on the internet that left a trail of ATF everywhere they drove it. They called the supplier to no avail so they just parked the truck for a couple of years and then finally decided to pay us to rip the transmission apart and fix the leak.
These are the same people that demand a demo for a week or too from their local dealer or better yet want to "rent" it for a month to see if they like it but then they trust every word the guy tells them that's 1000 miles away.
