I am in a dilemma now on which one should I keep? MDX with 58k miles/ 93k km or X5 with 81k miles/ 130k km. both 2007 and both fully loaded top of the line. Entertainment package on both. 3.7 vs 4.8? V6 vs V8?

I love the drive of BMW but the realibility of MDX. Wifey wants a smaller car, I am thinking of a Mini Cooper Countryman All4.

What's your guys call if it's you with this situation?
