I think the CARS program sucks and has nothing to do with trying to protect the environment at all. My 17-year old Saturn burns massive amounts of oil, spews heaven knows what horrors into the atmosphere, *barely* passed smog by a whisker and only because I disconnected the vacuum lines and stuck my fingers over the intake/outake ports for five minutes while the evap test ran, yet it's apparently not a clunker, because it got 28 mpg combined in 1993. But as a taxpayer, I get to subsidize the folks trading an 18mpg car in perfect operating condition for a new 22 mpg car. Yippee.
