The Cash For Clunkers bill passed the Senate as part of a larger spending measure. The details, explained in our Cash For Clunkers Guide, remain similar except funding's cut from $4 billion to $1 billion in the new joint bill.

Supporters of the bill hope its success will encourage Congress to continue to fund the program. Given the obstacles, we're a little doubtful.
