Hey, that's terrible they're still giving you the run around.
http://www.contour.org/FAQ/recall/99M03/Recall-ONP%2099M03_files/r99m03r.htmThat is the letter for dealers, and owners I think, so read it since it will probably be of value to you.
Another option is to give them your VIN, and have them run an OASIS report for your tour and ask for the orignal warrenty start date. It won't matter whether you're the first owner or the last one since that will tell when the warrenty on the car was started.
I hope it'll work out, but still keep us informed.
