Depends la bro. My own 530 has done only about 40,000km in 3.5 years. That's because my daily mule is the 325 I have other pals also who have 4 cars sitting in their porch, so mileage also quite low. But then again, too low mileage would also give its own problems. So in general, as you said, doesn't really matter about the mileage as long as car is well maintained
