As to your first query regarding the humor in my sarcastic comment, I will let it speak for itself. However, in regard to your second comment wherein you attempt to "defend yourself by asking a question that has no validity in the real world, to which anyone who has ever looked into buying used cars can attest to, I will just point out the ludicrous statement you made is just that.
P.s. I'll be surprised if you can actually figure out what I mean!
