Certified used car buying guide

Powertrain warranty: Honda offers a seven year, 100,000 mile powertrain warranty on its CPO cars. That's two years and 40,000 miles more than the original warranty.

So if you're looking at a four-year-old car, you'll get three years of powertrain protection.

Bumper-to-bumper warranty: You also get one year or 12,000 miles of coverage from the day you take your CPO car. Since the original bumper-to-bumper coverage on this car has expired, that's all you get.
