stef,
the X5 xDrive35d cannot be ordered with sport suspension anymore (as of 2010). Item 225 in option package ZAP 'sport actvity package' is a delete for sport suspension. In other words, the 'adaptive drive' system is the only way to get better cornering now. Unfortunately, it is also $3,500 in addition to option package ZAP.
