These days, with internet etc. people will travel fairly big distances to look at the right car, having read enough of your posts I'm pretty sure your car will be accurately described, their choice (and risk) to travel so far, they aren't doing you a favour, don't let it influence your negotiations over price.
Finding "normal" people with a reasonable attitude to sell a car to seems to have become harder over recent years, when I sold my Vectra (advertised at a reasonable £400) on gumtree, a buyer was outraged I hadn't changed the cambelt, I pointed out it was chain drive engine, but this wasn't good enough for him, he demanded to know when the chain was last changed, my answer only elicited more outrage from him, entertaining as it was, I eventually tired of his company and asked him to leave the premises, the eventual (normal) buyer, drove it, made an offer and we settled at £380, easy. The point being, you may have to deal with a few clowns before your serious buyer comes along, hopefully not! Good luck.
