What sticks out, is that you can buy an E85 Impala or Sebring, get the credit, but not necessarily use the ethanol, right?
This was the scam in Arizona. A law was passed giving tax breaks to people who had dual-fuel systems retrofitted to their cars. People got the breaks, but no one ever used the other fuel. The person who got the law written was connected to the outfit that did the retrofit. Wa-la, quid pro quo corruption.
