I purchased an 8 month old Magnum SXT with well less than 10K on the clock. I fell in love with the looks of the car and the roominess and cargo hauling capability. The car has a good, solid highway ride and decent handling for a large car. The downside has been very spotty quality. Issues have included a new torque converter at 9K, leaky rear diff at 12K, an annoying squeak in the rear of the cabin that the dealer has "fixed" 3 times, and a very "clunky" 4 speed tranny. The visibility is really annoying as well. While I really like the car I'm wondering about the long term reliability given the big ticket warranty repairs I've needed.
Style, style, style. This car is a stunner. The 3.5 liter motor has plenty of kick and returns decent mpg. It is a rock solid driving experience, very comfortable to drive, has great cargo capacity and a is fine highway cruiser.
Well, it's discontinued so I guess improvments are a moot point.
