I'm looking to replace my MDX that I've had over 14 years with a GLE, and intend to keep the GLE at least 10 years. I live in Colorado and make frequent trips to my cabin which is at 10k feet in the mountains. I like the extra performance of the -400 vs. the -350. A couple questions: How is the performance of the -350 in high mountain driving? How is the long-term reliability of the 350 engine and 7-speed transmission? Any issues with the 3.0 biturbo and 9-speed transmission (both relatively new, right?).
Thanks!
