"It's the year 2014, and the brand-new Prius plug-in is sweeping the nation. Thanks to its new Lithium-Ion battery, gas mileage has soared to 100 mpg, and Toyota is selling them as fast as they are rolling off assembly lines. People are lining up to trade in their "old" 2010 (and 2011, etc.) Priuses, which get a paltry 50 mpg, for the new model, but dealers are lowballing the trade-in allowances because nobody wants to buy a used Prius that gets half the mileage of a new one. Film at 11..." The above scenario illustrates part of the dilemma I am wrestling with as I decide on my upcoming car purchase. From what I read, 2012 will be the "Year of the Plug-In Prius" with LiO battery. With the Chevy Volt coming out this fall/winter, I'll bet Toyota is working overtime to follow suit. So, should I buy a car that may become "extinct" in just a few years, or wait a little while longer? A complicating factor is that the lease on my present car is up in December, so I have to buy a car by then. My options are to 1): Buy the leased car, 2): Buy a non-hybrid, e.g., Subaru, or 3): Buy a 2011 Prius "dinosaur" car. Then...five or so years down the road, buy a plug-in, hoping I don't get hosed on the trade in. Thoughts?
