AutoNation, the largest owner of new car dealerships, has come up with a great new program, whereby “green leaf” logos will be put on cars that get good fuel economy. The owner of AutoNation, Mike Jackson, knows how our dependence on oil from foreign countries is weakening our position in the world. So, he wants to encourage people to drive efficient cars. Clark is 100 percent behind him. Now, if you own a car that doesn’t get great fuel economy, don’t suddenly dump it. The gas costs are just one part of the whole picture. But when the car is on its last legs and it’s time to get a replacement, that’s when you want to buy a more economical car. You can’t control the price of gasoline, but you can control how much of it we use.
