Non-turbo Subaru is a good way to go.
I sold off my STi because the damn thing was pickier and cost 3x as my rig...MY RIG!! Specialty parts, high performance this and that just cleaned me out. On top of that, it sucked on the highways. An STi is either stopped, or going 85 mph...there is no in between. This is cool for like, a month but when everytime you go to buy a taco it turns into a race, it is annoying.
The non-turbo ones are a far more relaxed, comfortable and cheaper car than the WRX/STI vehicles. No worry of turbo, don't need a radar detector and looking over your shoulder ever 3 seconds for the law, and not every little fucktard in a god damn Honda Si is trying to get you to drag race off the line. Putting premium in it always pissed me off. Oh, and I couldn't keep my foot out of it so 15 mpg...on the highway was pretty common. New ones have shit ton of electronic crap that is in the way and does nothing but take up space, and eat tires and brakes every 10k.
The outback/legacies are good if she wants a mid-size, probably the way to go. The entry level 4 banger has plenty of power but the new 6 is ballsy. If I were to go get a Subaru, I'd just get the entry level 4 cylinder unless I lived up in the mountains, then the 6.
If ya'll are fat/have fat friends, avoid the Imprezas. I'm a touch chunky but all my friends are pretty much morbidly obese. They couldn't fit in that car unless they rode in the trunk. But if ya'lls are within 10% body fat of your target weight then it isn't a problem.
Subarus have crappy sound systems. They just do. If audio is important to you then go ahead and plan on ripping that crap out first thing. All it is going to do is piss you off.
If you do get a Subaru, get the trunk liner! Its a cargo thing that goes in the back and it is AWESOME. Must have.
To be honest, I'd put a woman in a new Forester. I drove one (as a loaner) and it was very nice. I drove it with the entry level 4 banger and an auto. Plenty of power.
Lastly, my Formula Ford made the STi it's bitch everytime at the track.
