I'm new to the Prius. I really want to get one. Havent considered it until recently, but I think its a real option fo me. I found a 2008 with 53K miles , has the LCD monitor (GPS), hands free bluetooth for $20,000. It seems to be in good condition. Its at a local Toyota dealer, and is certified. Just curious if thats a decent deal? Opinions? Thoughts? thanks!
