2009 Saturn Aura XR

I just saw some used 2009 Saturn Auras with more than 36,000 miles on them for sale at Hertz Rental for $11-12k. Of course, these cars have been driven beyond the basic General Motors 36k mile warranty. My question is, are these vehicles still good deals if I buy an extended warranty?

This was the first Saturn demonstration prototype vehicle. It was completed for evaluation and shown to the media on September 15, 1984. General Motors Chairman and CEO at the time, Roger Smith, and GM's then-President and Chief Operating Officer, F. James McDonald, are pictured with the 1985 Saturn four-door sedan concept.
