Well, I am subscribed to the "trucks for sale" section. Specifically the 67-72 & 73-87. I look at how many miles away the truck is from me and I really don't think it is right. Like this (http://67-72chevytrucks.com/vboard/classifieds/showproduct.php?product=3832) add tells me it is 84 miles away. I think Kansas is a little farther than that. I am in 75048 (TX). I have noticed this for a long time.

So, is something wrong with the mileage calculator or something?

I believe that it has been messed up since the classified area was introduced. If I recall correctly it is a software error not easily fixed, but somone with better knowledge of the situation can probably offer more insight.
