Who cares where they are. For $1,000-$1,500.00 you can have them shipped to anywhere.
If any car you're looking at is a good deal then another $1,000-1,500.00 shouldn't break the deal. Otherwise the car you're looking at isn't that good of a "deal", in my opinion anyways.
The rust free cars I have bought from out west were far, far cheaper (even after paying to have them shipped) than buying one within 600 miles of here.
