Silverboxter, did you ever drive the car in a spirited way? I know you said you never redlined it, but did it ever see any RPMs approaching the redline? That could be a part of the problem. I'm not talking about beating on the car, but I am talking about putting it through its paces and getting a good, heavy-breathing run once in a while. I see that as a part of the rules to follow, too. If the car never saw high rpms, despite being daily driven and well maintained (hat tip to you there on both counts), that has been another suspected factor in the failure of the IMS and other areas of the engine.
