Our 11-year-old car just passed the 200,000-mile mark on the odometer. It’s been with us for multiple transcontinental drives and a lot of smaller road-trips in between. This is our unicorn: a combination of manual transmission, smooth straight-six engine, all-wheel drive, and cavernous station wagon that’s simply no longer available from any manufacturer. What will we do when this car is ready for retirement? That’s a tough question.
