I have 106K on mine and only a lift pump at 70,000. It gets washed once a year whether it needs it or not (or when it rains). Other than a tear in the vinyl on the console lid (because my knife fell on the lid and poked a hole in it, my interior is sharp. The paint is so-so (partly because its Patriot Blue, partly because it got keyed several years ago). On the whole, it still looks pretty good.
We are setting outon a 5,000 mile trip around the southern, soutwestern, and plains states at the end of the moth and I am looking forward to it!
Mustang Diesel - I have the PSM also. It helped lower my egts about 150° when loaded. I have been happy with it since I put it in (about 50k miles ago).
