I like the 300M, especially the Special, it hit all the right boxes for me....spacious, good power from the 3.5L, really well equipped for it's time, comfortable, nice ride. Hardly ever see them now days.
One of those platforms where it really matter how you spec'd it out. A basic Intrepid, awful, especially with the 2.7L. But a loaded up 300M, or even a Concorde...pretty nice.
