you guys are assuming way too much...i dont include the safety in my price, and i dont do a safety until i get the money to get the safety done (reason being is that safetys do expire, and it has taken me as long as 6 months to sell a bike before). If they have a mechanic they want the bike safetied with, then they pay out of pocket. what usually ends up happening is that they want the thing safetied as fast as possible, so I get the one and only guy i know that does house calls, plus he's cheap (which the buyer is usually fond of). I've never had someone come back to me saying there were issues with a bike that I didnt mention to them before.
I'm just saying, that's the majority of buyers out there, buy now, ask questions later. Usually, their minds are made up before they even talk to the seller. It's not uncommon for people to buy bikes unsafetied either (in which case, they get it safetied themselves after purchase).
say if you hired a general contractor to renovate a house, and he had a painter that does a quick and decent job with good rates, but you wanted to paint the house with your own painter meaning it would cost more but the job was better. I merely reference Ted as an option, I've never forced anyone to use him. But guess who theyre going to choose, Ted who costs $60, or Z1 who costs $100+.
tl;dr, people i've dealt with in the past don't care about their safety. If I actually had a buyer who was anal about these things I'd let them do whatever they want until they were comfortable with buying the bike...okay?
