Misaligned hoods are easy to fix.
Exhaust drone can be fixed. If nothing else, I always take it as a sign that I need to accelerate.
I can't say I've ever heard of broken wires until just now, but I don't do the .morg so that probably plays into it. Sagging doors seem to be an occasional problem at worst, and from the techs I've spoken with, it seems to afflict those who slam their doors, rather than closing them as if they were made of plastic and fiberglass... I've heard of a few cases, that's it.
I'm not trying to say you're wrong, but I suspect you're getting into rare problems, not things a potential new owner needs to actually worry about. I think this guy is worried more about major maintenance issues. I'd say as long as the car had the steering rack recall done, the only other major Gen II issue worth being concerned about is the plastic impeller thing, and I gather there were few of those.
