I have 5k on mine in just 6 months of ownership. Unfortunately, we have to get a new windshield as we picked up a rock on the highway in February after a 3k trip only 4 miles from home.....this isn't the vehicle's fault though.
I'm still trying to decide which vehicle goes to the coast later this year when we go. That will wrap at least another 3k miles in 2 trips. As a diesel goes, that's just approaching break in....
'00 528 now in other hands,
'07X3si now in other hands,
'14 535d XDrive,
'18 X5 35d In break-in...
