WAF (wife approval factor) is tough. Does she like to be comfortable, want to feel fast/G-forces, want something cute, etc...
A lot of G-body 911s have been thrashed through ten owners. Many have lots of sorting to do and prices are way up. Aftermarket support is great and tech support is comparable to our forum, that is to say, really excellent. You can customize them in so many ways and really get upside down making it yours if that's what you like. Many of my friends have classic 911s from before the market on them really took off and I've always been envious of that scene.
But if I ever buy a Porsche, it'd probably be a 928. I've always had a soft spot for them. It's like the fuselage of a plane!
The women I've known always seem to like curvy, cute, stylish, and no smells ideally. Namely, the 356, 190SL, plush 50s American personal luxury coupes, the early E-type coupes until they get in one, Karmann Ghia, Fiat Jolly and similar beach cars... then that other demographic that likes Broncos and Blazers and Defenders and such, at least the idea of them.
But yeah a well-sorted 911 is a really nice car. Everything post-1977 is totally galvanized, which is really nice. I recall the AC not being great on the 80s cars I've known but I'm sure there's a fix. A lot of people REALLY like the 3.2 for feeling the most "modern" of the bunch, or at least that's the word most oft-ascribed that I've seen. Might want to drive one.
But like Jordan said, looking into the smell of your car would be a lot cheaper than buying a 911. I'd look into that unless you'd die of angst from not owning one.
