Well think about it.
If the guy was trying to sell it for a fair or cheap price to get rid of it fast he would post a price.
If he was thinking his sled was worth more than it actually is because he put a summer sucks decal and a boss seat on it he's got to get you to call him or write to him to get you involved with the sled so he can quickly tell you all the reasons why you should give him more money than the sled is really worth thereby suckering you in.
If you saw what he was asking for it up front and it is well over what you would ever give him (or anyone) for that sled then he'll never get the chance to explain to you why his sled is worth more than it really is.
I NEVER respond to an ad that has no price because I always assume the seller wants more than he paid for it because of sentimental reasons or because it has a trunk bag and a hot dogger as mods.
Why else wouldn't he post a low price....Too many responses or phone calls?
Yeah...I'd hate that if I was trying to sell a sled.
