We just completed a 7,000 miles road trip (Atlanta->Yellowstone->Mount Rushmore->Niagara Falls->New York City->DC->Atlanta) in 23 days. No issues with the car at all. We took delivery of the X 75D back in March but car is already at 16,000 miles. I wonder if I should bring the car in for the first annual service. My question is for those of you who drive, say, 36,000 miles a year, do you bring your car in three times a year for service? The reason I ask is that the annual service cost is not inexpensive, the cost of multiple services per year kind of defeats the cost saving from not burning gas. Thanks for any thoughts on this.
