Yeah, the 650 series is out of my league. I do have about 30 hours in a III but that was a lifetime ago. They are nice airplanes and the VII is the nicest of them but as Josh said, parts are something of an issue. I always thought they were a little short legged for an aircraft of that size and class, which may be why Cessna moved away from them.
All that said, a nice low time VII could be a real nice airplane for somebody at the right price.
