I have to pass on this bit of ?clunker math? sent 
tome by a subscriber:
?Think of it this way 
- A clunker that travels 12,000miles a year at 15mpg 
uses 800 gallons of gas a year. A vehicle 
that travels 
12,000miles a year 
at 25mpg uses 480 gallons a year. So, the average Cash 
for Clunkers 
transaction will reduce US gasoline consumption by 320 gallons per year. 
They claim 700,000 vehicles so that?s 224 million gallons saved per year. 
That equates to a 
bit over 5 million barrels of oil. 5 million barrels is about 
5 hours worth 
of US consumption. More 
importantly, 5million barrels of oil 
at $70 per barrel costs about $350 
million dollars. So, the government paid 
$3 billion of our tax dollars to save $350 
million. We spent $8.57 for every 
dollar saved. I?m 
pretty sure they will do a great job with health care 
though...?
