We had an E70 until recent in the family since new. 3rd party extended warranties took care of most service costs, however around 80k miles the car just started becoming a headache. It was always serviced at a BMW dealer, one owner car, etc. Didn't matter.

I do still see E70s driving around though, so it seems if your example is lucky and you know a good mechanic with fair pricing then it's doable.
