Sorry to read that you're selling the bike, Phil. I hope it goes for a reasonable amount. Without wanting to cause any offence, the bike is worth what it fetches on the day.
I do have to say that when selling vehicles I have very often met "doubters" who for some unknown reason try to knock the asking price down to what they think would want to pay, even if they have no intention to buy it (that's the good thing about selling by auction).
My son put his pride and joy up for sale a few years ago (a lovely BMW 2.3 coupe with a straight six engine and it was near immaculate) very clearly stating NO OFFERS on the advert. We had looked around when pricing it up and if anything it was under-priced. Almost within minutes he was being pestered by some chap who phoned about three times in quick succession, then wanted to come round to see the car. We waited in for him (I was on the driveway, working on my own BMW) and he soon arrived in a very tatty old 5 series saloon. He immediately tried hard to find fault, pointing out every tiny stone chip etc (there weren't many, even though the car was almost fifteen years old and there was no rust). I pulled my son to one side and said quietly "this one's a real tyre kicker, he won't buy it - just don't reduce the price one bit".
After about half an hour of him checking the car out, he made an offer of about half the asking price. My son and I looked at each other and my son said "Sorry, the price is fixed, as per the advert".
This chap started explaining how he was a BMW expert and he KNEW what the car should be advertised for. I asked why he had come to see a fifteen year old car that he obviously thought to be overpriced when the advert said "No offers". He got in a huff and drove off, saying "You'll never sell it!"
It sold the next day, for the full asking price; the next chap to come round and look took five minutes to agree it was well worth it, paid cash and drove it away. The tyre kicker had the cheek to ring up later and ask if he could come round again and have another look! When my son told him it was already sold, he took a very strange attitude, saying "No way was it worth that much!"
But it obviously was.
Built like a gun... could go BANG!
