While I've liked my Prius, I would not buy another one, and I would warn anyone against buying a used one with high mileage. In some states (including California) the battery is warranted up to 150,000 miles, but most states it's just 100,000. It's not IF your battery will die, but when. Why pay the premium for a hybrid, and take the risk of a costly repair, when many gas engine models get nearly 40 miles per gallon? The answer is that you shouldn't.
Just another bit of advice from Dave. You're welcome.
