I got a quote a few years back around my way for a manual pop-up/removable moon roof for around $375 with a lifetime guarantee for leaks, malfunction, even paint around the trim. I considered buying my own and just doing the install since I have past experience, but I simply do not have the tools and it's always nice having a warranty/guarantee as a backbone regardless. Getting hokey with some t-tops in my VX and blasting it back to the 70's would be even more fun, but that is some painful works and I don't think the VX's a-pillar frame is stable enough for such.
Disclaimer: I have done MANY tt-top/moon/sunroof installs on many cars in the past, and they are relatively fast and easy, for skilled installers that is, heh. If you have never done it and do not have the proper equipment, totally, let the professionals do it. You will be kicking yourself silly when you mess up just the slightest and suddenly the you have a gaping, scraped up, dented hole in your roof that your moon roof simply falls through onto your lap.
