I had a 2.5 for 8 years and 120k on the clock. It was our workhorse and we abused it with camping, hiking, and our Alaskan malamute. Despite this rugged treatment the car held out really well. The panoramic sunroof had to changed under warrenty as it was rattling. The water pump was replaced twice outside of warranty and the oil pressure relief valve was changed at 100k. All in, it was a great car. I upgraded it to an X5d about a couple of months ago. I would own another.
