Std Honda warranty for my ULEV 2004 HCH was 36K B2B, 8yr/80KM battery.

Since I keep my cars for 10 years I projected mileage at that time to be ~160K.
Because I still wasn't sure about it all I spent ~$900 on their best ext warranty.
This covers 7yr/70K b2b, 10yr and 150K on battery.

This was last January.

Efficient drivers do it better.
1003 miles a tank personal record. 74MPG calculated. HCH1 CVT
