yes, no more intrepid
but no, their didn't replace it with the magnum. the magnum is a brand new car entirely on its own. The new platform and ideas used for the magnum/300C caused the end of production of the treps so that new platform(including rear wheel drive + V8's in sedans) can be used in whichever new cars they come up with.
also, the new option of allwheel drive is available with the magnum. so i think which ever midsize or full size sedan which SHOULD replace the intrepid will have great expectations
