Consider the following:
Since our cars are older, aftermarket companies are starting to drop their lines of parts for them. The focus community is not a huge one, and quality performance parts are a very small market share vs other vehicles that are much more popular.
Because of this, focus components are starting to get harder and harder to find, especially those that have been discontinued.
In some respects, I will agree that ive seen alot of people post up items for much more than they are worth, but big deal, unless its the last part on earth that you absolutely must have.. move on.
