Mustangs are fun to drive. Voyager is a sleepy ride, but good for family and space. Saturn I heard is just about as reliable as a Toyota, but that the ergonomics were somewhat left to desire. I did drive one once, a friend's, and it was quite all right.
My e34 is really fun to drive, and comfortable. Plus there's this great forum to share or get info from. If I feel like burning a bit of rubber or do some cornering, I can. That's me: it goes well with who I am, what I believe in and what holds dear to me. And I love to tinker on it.
But not everyone is for BMW, and surely if she feels comfortable with a nice Saturn, she should go for it.
If American cars were that horrible, surely there would be none on the market. Difference and tolerence, people.
my gf has a saturn and i make fun of it every now and then, BUT it is that little bugger that keeps boosting my ass when my battery is dead due to some electrical issue that i am working on right now. Seems like an alright car, its simple and economical.
Not sure how the passive safety would compare, being that they are very plasticky
