In my case I read the thread because I was interested in the Brake problem and fix based on your question. I read many of the threads about problems so I can learn more about my truck, what to look for, what fixes it etc. It wasn't until I read you mention that you haven't bought the truck yet and then posted pictures of it that I chimed in. You seem to be a "newbee" to HMMWV's, just a guess. Grocery stores number one source of income is Impulse Buyers. On the surface all HMMWV 's look pretty much the same and that is exactly what I thought when I was looking. I now know a lot more about them and realize there are huge differences even with ones that look identical. Lots of changes and improvements over the years. The 1980's being the very beginning they tend to be the most lacking also. I think many people tend to see only what's in front of them sometimes and make impulse decisions. Even then I wasn't going to chime in because it's not that bad of a price overall but then you mentioned "flipping" it.
Whether you asked for the advice or appraisals or not is irrelevant because many of us come here to help our fellow enthusiasts. I think everyone that commented did so in an effort to help, not to mock or make fun of. After you buy it, our comments are meaningless. Keep in mind probably more than a few of us have already been there and did that and learned from our experiences.
