Just going back through the OP's posts here over the past 2 years as a member, I do understand the frustration that he is describing....however none of the issues are really that detrimental....and not unlike those that are described in the majority of the stickies in this forum or the first few pages of reading here.
With that said, it's hard for me to justify the belief that someone can claim that a vehicle has been meticulously maintained, when they purchased it second hand. Reading back in the OP's posts since he joined this forum, it's apparent that this was not purchased as a new vehicle, rather a used one. So OP....how can you claim that a vehicle has been meticulously maintained since new, when you (or your grandma) weren't the original owners. Furthermore, even though someone is the original owner of a vehicle...how does that justify that it's been maintained well at all? In fact, you have pretty much done all the tooling on this truck instead of a certified mechanic. Even as far as the intake manifold gasket replacement. Kudos to the average shadetree mechanic and their desire to save a few bucks, but it doesn't mean the work was done right. So I'm not sure I would call that 'meticulous maintenance'.

You're on an Explorer forum where others share their frustrations, but to make a blanket statement that the Explorer is crap and that @ 66k miles you (or should I say your grandma....) are frustrated beyond belief and are prepared to exhume Henry Ford's body from his crypt in order to slap his jaw around a little because of a few fairly minor (and VERY common) issues plague you...is sort of silly.
I still like the vehicle, hence me picking up my 93.) good day all!!!!
