porsche cayenne or BMW X5?

I am looking for a 2008 Porsche Cayenne CPO . Confused ..should i get the 6 cyl or 8 cyl? My wife like the BMW X5 SUV.... I really don't like the BMW reliability ...

BMW X5. Reliability, better warranty, better steering.

depends if there's a large boat or a large horse trailer that needs to be towed then cayenne
if there's smaller boat or smaller horse trailer that needs to be towed then x5
google '2008 cayenne aol spec', 'x5 aol spec'
turning off javascript prior clicking aol websites, should produce better layout

Porsche Cayenne isn't a good idea.If there is any problem,you will need to go to dealer because parts are really hard to find and normal mechanics don't work on Porsches,unless you want to them to make the problem worse but if you have the money for maintenance go for it man,it's better than an x5
