Hello, I'm planning on buying a Prius III with navigation within the next 3 to 4 weeks. I've found one for $100 over invoice and next weekend I will be visiting a dealer to check on the Costco price that they offer through the Costco car buying service. I'm looking for any advice anyone has specifically regarding the Prius III. Should I consider an extended warranty or is it a waste? Thanks!
