Wife is having a baby so want to get crossover SUV, but would like car to be fun to drive if possible (my current car is BMW Z4.)

Also considering BMW X5 and Porsche Cayenne. Not sure worth the extra money though for these.

(1) LEXUS
(2) Infiniti
(3 )BMW X5
(4) BMW X3
(5) Porsche - Too many problems.
