Surviving $4 gas shock:
Consumer reports did a review of the Chevy Volt and essentially said, What the heck?! It doesnt make economic sense. Even with the govt subsidy, the cost would be almost twice what the Prius, etc are running.
To survive $4 a gallon gas, the most efficient vehicle is one that is paid for. To go buy a new car just to get an additional 10 mpg is not a good idea. You have the cost, interest, increased insurance costs, etc on the new car to save a little. If the car is paid for, insurance costs decline sharply, no payment, no interest costs, and, unless you drop the tranny or blow the motor up, repair costs will still be far less than if you have monthly payments. Alternatively a decent used car is still much more cost efficient than buying a new car. Someone else has taken the 50% new car hit, without using up 50% of the car.
