My plan: In 5 to 10 years I'll replace the battery as part of a PHEV upgrade of my 2G Prius. And through the car's lifetime, I'll have about 1/3 the brake maintanence, and none of the rubber chain repairs.

AFAIAC, the HV is a non-issue.

The electronics, OTOH, make me nervous enough to purchase an extended warranty.

2004."
