I'm undecided on this issue. Traded in a 2005 X3 2.5 for a 2006 X5 4.4 with 32k kms in it and it was bulletproof for the first year or so. Now the air suspension is killing me... after changing both front struts ($3k aprox) in a couple of months, a "suspension inactive" message wont go away. It has been in the dealer twice (about 13 days combined) and its going back on monday. They have reset the entire sistem several times and the message goes away for a few days and then its "sits" on some tire. Even though it's a real dream to drive and I cant imagine going after a Pilot or something, i'm getting frustrated with this issue. I guess my only regret was getting the model with the air suspension. Should've kept the X3 for a year or so and then upgraded to an E70 with the 3.0 diesel engine.
