I talked to my friend who is a Finance Manager at a Honda Dealaership and he said that its not just for Certified cars it for all Honda cars.

Honda offers 100k/7 years powertrain warranty on all thier Cars. If you sell the car, the warranty continues to the next owner until 100K or 7 years.

The powertrain warranty is good for 7 years or 100,000 miles from the original date of purchase of the new vehicle. form Honda's Website.

It means if your car it within the time or miles, you are still OK but if it is passed then you are not.
so if a vehicle was purchased in 97, it will not have a warranty anymore but if it was purchased in 01 and its under 100K, You still have a warranty.

Here you will get alot of different opinions but the best way to make sure is either call American Honda or a Honda Dealership, which is what I did.
