Called the “Consumer Assistance Recycle and Save Act of 2009″, or more commonly, “Cash for Clunkers,” the $1 billion program will provide a voucher of up to $4,500 (effectively just knocking that much off the price tag — dealers will get electronic payments from the feds) to help offset the cost of new car purchases or leases over the next five months. The cars that you’re limited to must cost no more than $45,000. So that means I can’t trade in my old 1998 Dodge Caravan (MPG rating of 18) for a 2009 Lotus Elise (MPG rating of 26) because the MSRP is too high ($47,500). However, that awesome new 208HP 2009 Mini Cooper S John Cooper Works (MSRP of $29,200) would not only get me the basic $3,500, but it’s combined cycle of 28 MPG (10 more than my current car) will get me an additional $1,000 for a total of $4,500 off the price of the car! Not a bad deal, in my humble opinion. This rebate also works with other rebates from the manufacturer or hybrid car rebates offered from the Federal Government.

So what is going to happen to all these old cars now that they are off the road? Most will have their engines taken out and destroyed (to ensure these “high polution” drivetrains stay off the road). However, miscellaneous parts like doors, bumpers and other non-drivetrain parts will still be around to make sure those cars that are running can be repairs and made roadworthy.

The House bill would go into effect within 30 days of enactment but it is not retroactive for new purchases made earlier this year. For a more complete description of all the applicable situations, see the chart below:
