My 2007 3.0SI with AT just turned over 130000 miles this morning on the way to work.
So far, so good.
I will be changing diff fluids again in the spring, transfer case and AT fluids again in the summer and need to replace the brake pads and rotors in the spring.
It has really been pretty trouble-free so far. With the exception of the rear door vapor barrier, nothing but normal maintenance.
