Our X5 just broke 66k on our 2003 3.0i last week. Our last big repair was back in January when we replaced the oil separator and the front transmission seal and rear main seal at 57k miles. This and a fan clutch assembly at 52k miles were the big repairs and everything else was a wear item that would need to get replaced over time. Our X5 has been trouble free for its whole life and I hope we get many more trouble free miles.
