Sometimes if it's too cheap people think there's something wrong with it. I know a guy that once had a old Chrysler for sale for $5,000 no one would look at it so he re advertised it for $7,000 and sold it straight away.
I've also learned that sooner or later everything sells. Sometimes I look through the retail items in my shop and I'll pick something up and think "damn thats been on the shelf for 8 years, they'll bury me with that." The next day it's gone.
I've advertised bikes and not even gotten one call. Six months later put it in the paper and the phone goes hot.
I took a swag of pre 80 dirtbikes to a two day swap back in 2000 I couldn't give them away. I had a guy tell me that the 75 250 Elsinore in original running condition still with the safety stickers on the tank was way overpriced at $700 and that I would never sell it. He knew because he held some high position in the VMXclub. (This was before the pre80 class I believe.) I told him that $700 would buy a lot of spare parts for a 74 Elsinore. I took all the bikes back home, put them in the trading post and sold them all in one day. I even sold bikes I didn't advertise. I regret all this now though. $600 for my MK9 370 pursang, $500 for my 75 pomeroy replica. $600 for my yamy mx250c My gold medal frontera AAAAARRRRRGG
