What are your thoughts on upgrading from an E53 X5? I think we will be selling our 2005 3.0i which has been pretty solid the last 3 years.

Looking at the 08-11 GL450 vs. an E70 X5 of the same era. The E70 interior and reliability seem to be poor.

Have owned 20 BMW's over the years but MB is now a consideration.

Discuss!
