I went thru the exact same situation with my wife, but it was my car so I really didnt care how she felt about me getting a stick. She gets her way with just about anything else so...
But I'd definitely get the 1LE if I were you, its a blast to drive!!!
From the sound of it, it seems like your wife knows how to drive a stick (mines doesnt, hell I didnt till I bought it basically) And if she doesnt, and push comes to shove just teach her.
