17000 seems like way too much money for a car with 100,000 K. Also, there is concern that when hybrids his a certain age they will need a battery replacement which will be mucho expensive.
Also, first gen priuses are ugly (in my humble opinion.)
For $17000 youy could get another vehicle with almost equal efficiency and without the problems that new technolog have. I think I'd just buy a Civic, but that's me.
