I think the wording of the ad is obnoxious. Too many exclamation points, FEATURES IN ALL CAPS, etc.
Your price is right (right smack in "excellent" in Kelly Blue Book), you've got the maintenance records, and, frankly, I'm surprised that a manual tranny might be such a downer (they're really not difficult to drive, and are slightly more efficient, too).
I just don't think that anybody's buying a car now.
