Please produce a detailed comparison of the bmw x5, acura mdx, volvo
xc90, and whatever else belongs in that category. The comparison must
include:
 - All available safety information, not just the usdot crash test,
but other crash tests as well as info on safety features
 - GPS nav system comparison. Which ones are better, and do any have
major defects, such as not allowing you to set it while the car is in
motion.
 - Potentially uncommon features, such as a backup camera.
 - Seating and cargo information. What are the dimensions of the cargo
area when all of the seats are used?
 - Reliability. How many new owners have problems and how often do the
cars require service? (including oil change and the like)
 - Interior noise -- how loud is it when driving at highway speeds?
(numbers would be nice, if possible)
 - How hard is it to connect an ipod or computer to the car stereo?
 - Comfort, performance, mileage, price, etc.

Please provide the comparison in the answer, not as a bunch of links.
