I am helping a family member look at pre-owned Prius cars. I searched, but did not find something that was a clear "Buyers Guide" that seemed clear. So here are a few quick things I'm reading and would love to have added feedback. 1. Battery Warranty for NJ 10 years/150,000 miles (?) 2. Fluids replaced Oil 10k interval Brake fluid ? Differential? Transmission?3. If it has been sitting, this will affect battery charge? 4. What is anticipated costs of battery replacement? If someone can share intervals for the fluids, it would be appreciated. Anything I am missing or need to look at with pre-owned Prius?
