take them both for a test drive. they both have s star saftey. the tribeca looks are alright, better then previous model. it has dual aircon, rear dvd player, navagation, reverse camera, heated seats and mirrors power seats more luxury then the foz. but foz can be modified to go faster and handle better but why would you, you dont want a loud car or worry about ground clearance or stiff ride. I wouldnt think your misses would be taking the car to the track but with the foz you do have a choice of manual or auto, tribeca is only auto.
you already have 1 hoon car plus tribeca can have up to 7 seats, so if more kids pop up
have you looked at mazda cx-7 or cx-9

touareg, my uncle had 1 when he was in america, said it was a really awsome car i think he had a top end model, so lots of power, airbag suspension, the works.
