Fair price to sell my 2007 Prius for?

I'm thinking about selling the old girl for something newer. Here's the "open book," I plan to be transparent with any future buyer on what I have done to it, and what I know to be wrong with it.

Overall: 2007 Prius, in NY its whole life, 196,500 miles, and the hybrid battery system was replaced by Toyota at 163,615 (7/22/16) with Toyota covering $2,000 in Goodwill. Front bumper has a small crack, and there is some rust, but not yet visible from the outside. Tires are new within the past year. Plugs, PCV valve, front pads/rotors, ICE, Inverter, Transaxle, brake fluids all done within the last 30,000 miles, replaced 12v in January. Full service records from Toyota since I bought the car in 2012.

Cons: The "brake bark" is getting worse, albeit fairly slowly. No warning lights or codes yet, but definitely getting louder. Tried to flush the brake fluid last week, it did not help, which means the Brake Actuator System is slowly going. Burns roughly 2 quarts of oil between oil changes, The little fuel door also does not open on its own, I need to jam something under the latch, then pop it open by hand. The heat doesn't seem that hot, and the AC doesn't seem that cold, even though the AC condenser has been replaced twice within the past year (once under part warranty).

In no rush to sell, so I can take my time selling, thoughts on price?

Thanks!
