I don't trust any BMW parts out of warranty (I think this company looks to parts & repairs as being a massive profit center) so I'd be a bit concerned about how durable that starter really is, but they've been using it in Europe since late 2007 so one could probably hunt around the on-line forums and see if there are any complaints about the durability. Maybe I'll do that later this week, if I have a chance.
Yes, that's correct... the Mazda approach is better from the point of view of starter load/long term reliability.
