I think test driving more cars is a fantastic idea. I'd add Toyota Rav4, Subaru Forester, Nissan Rogue (I think this is the Nissan model that compares to the others on your list) and perhaps one or two other comparable models from other brands. Think Ford, Kia, Mazda, etc. Even if you're sure you don't want any of those models, the experience will help your wife become more sure of whatever car she ultimately picks.
