It's not clear whether these will be offered as 2004, 2004.5 or 2005 models. Both will be on the new RWD LX-body platform. I have no information on pricing, but I'll wager the 300 comes in the $27-35K range. No idea at all on the Magnum; I'm a bit confused about where they are going to position that vehicle in the Dodge lineup.
As you can see, information about specs and pricing is spotty at best right now. But what do you think of the proposed styling? I really love the 300. I hope it looks just like the drawing, but with a slightly higher roofline and more reasonably sized wheels. I'm thinking of Photoshopping a '70s-Chevy-style slim chrome bumper onto the front of it...I think it would fit in perfectly with the styling, and provide some practical protection to boot (and a place to mount the front plate!).
The Magnum I'm not so hot about. The roofline is just way too low, and recent spy photos indicate that it's going to stay that way. The front end is nothing to sing about, either. It doesn't look very practical for a wagon. I like the Pacifica (which is NOT LX-body based) styling and layout better.
