Mechanics are like every other profession..... there are good ones and there are bad ones. Really bad ones. When I first got my Intrepid, I heard a mecahnic say that the LH's go though tie rods every 30k or so. Well, in 110k, my Intrepid went through just one. And that was around 90k. The LX's actually have much more problems with tie rods. I have 81k on my Magnum now and I think so far I've had 3 replaced so far. And yes, the LX chassis is part of an older Mercedes E class suspension. My transmission is also the 5 speed Mercedes design as is the stalk mounted (which I hate) cruise control. I believe the front suspensions on the LH's were derived from a Renault designed suspension on the Eagle Premier/Dodge monaco.
