We hope gas does not go up in price anytime soon. But if history is any indication, it will. Paying $2 per gallon for 87-octane is near nirvana, but many analysts predict gas topping $4/gallon in the not too distant future. And if OPEC has anything to do with it, it just may. Luckily, Toyota has your back. They understand the whole hypermiling MPG game. They also understand that the economy is hurting, so they will reward prospective Prius buyers with $500-2000 cash back* on all 2009 Toyota Prius models. Not only will you be save a ton of money on the purchase of a brand new Prius, you will save a few petroleum tankers filled to the brim, as well.
