Tips on Buying Cars: certified pre owned autos warranty, powertrain coverage, bumper coverage

Question
If buying a certified pre owned vehicle, should the dealer include a
extended warranty at no cost to us?

Answer
Most certified-pre owned cars come with some type of extended coverage from the mfg.  Either more powertrain coverage, or in some cases "bumper to bumper" coverage.  That being said, it never hurts to see if you can get them to cut you a deal on an extended warranty.
