When I told my brother in law I bought a 300M he almost freaked out. He thought it was a 300 which he also hates the look of. When I clarified the difference he said what a difference, a lovely looking car. I had a '95 LH, definitely not equal to the 300M mechanically, although the LH2 cars are closer. But after all they weren't sports sedans, so no comparison. Unfortunately the LH2 Intrepid is too squashed looking in the front, it's a Sebring test styling. The LH2 Concorde is too long and not as good a handling car.
I agree the 300 is a solid vehicle, but it looks it's part with a truck like front end and very shallow windows. Of course it's additional weight of several hundred lbs. drags down the 3.5L engine, which is more than adequate in the 300M. One day a 300C was parked beside my LH Concorde, as I approached from the front I couldn't believe how ugly the 2008 300C looked beside my lovely looking oldie '95 Concorde. Even if the 300 was FWD which I need, I would never buy it. Lets face it, there those who like a macho boxy car design, there are more who want a smooth graceful design. The pimps agree with you, as I'm sure you've noticed.
BTW I've rented the LH2 Intrepid several times for about 6 weeks total and a Magnum for 2 weeks. The Intrepid I could live with, but sorry the Magnum was not even close to my desires.
As for the large gas burning hulking over chromed heavy monster cars of the 50s/70s, I was never interested in them. Just not my thing. the European sport sedan approach to design is what interests me.
I find it interesting that so many popular cars of the last several years have adopted the 300M styling profile. Obviously it's well liked and Chrysler set the trend way back in the late 90s when they were still running their business themselves.
