what dealers dont know

hi went out to buy a new prius today, and came home emptyhanded.first there are 28 dealers in the greater los angeles area the first shop showed me a package two model the seats were real uncomfortable i was told that is it no lumbar support in any model,this is all they offer no electric adjusting it's weight saving OK i left there.went to another dealer sat in a prius v it had electric seat adjusters with a lumber suport was told there in all prius with package 5 ,but i could get a 2012 at a big discount that was the same as the 2013 i was sitting in.asked why the were selling so bad that they still had 2012s left ?asked what the difference was between a prius and a prius v just the back styling or a more significant stuff ,just a station wagon look he said. then asked the batteries are they nicad or lithium ion he said this years are nicad next year they will be lithium ion and cost more,decided to come home and ask questions on a forum as it became obvious the sales people dont know .so that being said are the seats with electric motors and lumber support available in a prius,with package 5.are the 2013 selling slow why are they pushing 2012s,are the 2014 going to have lithium ion batts thanks i really want a new prius but i can wait for a 2014 if there will be big changes,also when will the 2014 be at the dealers
