Actually... On one hand I can understand your frustration a little as I had to read the ad a few times to realize that your basically giving the parts away for just shipping cost. The way you wrote it wasn't very clear.
However, when a mod said a price was required, your smart *** answer of $15,000 on one and $30,000 on another was not necessary and since it was clearly you being a smart *** I'm sure that's why the ad was deleted.
So, I'll clean up the ad and restore it if you think you can agree not to be a smart *** in the future with these kinds of things. Deal?
