A bit of hilarity

I just received a call warning me that my vehicle just went out of warranty, and that I'd do well to "get it back in warranty".  OK, fine, but my vehicles are a 2000 Chevy Venture with 259,000 miles  on it and a 1997 GMC Sierra with 151,000 miles on it.  I'm pretty sure neither has had any warranty--not even rust-through--for at least seven years.
