I agree that $550 is too much for a used genoa of that size. There's no way to know if the shape is good lying on the floor.
But "feel" is also not always a good indicator either. If a sailcloth was made with a lot of resin then you want there to still be a lot of resin but the very best woven sailcloth has very little resin to start. This cloth depended on high quality thread and very tight weaving. The old Hood sails in the '80s were very soft but held a great shape far, far longer than today's woven dacron sails. Twenty year old Hood genoas could win club races. The Challenger Marblehead cloth is similar and is still available at about twice the price of standard high resin cloth that the sailmakers all use to keep the price down.
If the customer is willing to pay for more than cheap cloth, sail makers all recommend laminate sails - because there's a good chance they can sell you another sail in a few years when the laminate sail delaminates or mildews (try asking a sail maker if they will make you a laminate sail that will last for 10 years
