Very reputable shop. Paul, the owner used to be active here and on the "What Drives You" pod cast back in the days when Danny was a presence. A bit pricy for a 17 Y.O. Vehicle but for a buyer who lives in the area I'm sure he would take care of any minor issues that come up and with a genuine OEM battery, should last a long time.
That is a high premium for a 2005. New Parts aren’t readily available anymore. But it’s not bad if you need a hybrid car right now, at least you’re not paying $10k markup for air on a new hybrid
That is Toyota's standard policy. Not to worry about, should last the life of a 17 Y.O. vehicle, even with low miles.
