Favorites Page Closest Sort Shows Wrong Distance

Opening my Favorites page and selecting the Closest sort, the distances shown under each vehicle is very wrong, as if it does not know where I live exactly. As a for-instance, I am at 03467 and one favorite is at Canobie Lake Toyota (03079) which is about 80+ miles away. The Favorites page lists this as 18 miles away. If I were to guess, the algorithm is trying to determine where I live based on my IP address, an invalid approach. Shouldn’t my user account have a zipcode that identifies my home location? Or maybe the Favorites and Hide pages could have a lockable field designating the ‘home’ location so that it can be changed based on where someone other than me might live?
