I post this in this non-F30 specific thread.

At what point do the hoses and wiring and other plastic or non-metal parts start cracking and falling apart effecting operation/safety? Besides normal maintenance intervals, what else do you need to replace/refresh that you would not have to in the first 10 years?

My current car is the longest I have ever kept a car, at 114k miles and 13 years old. Had it since it was 1.5 years old. I always replaced my cars after 3-4 years, and I bought them either new or under 30k miles. So do not have experience with older vehicles (let alone BMW) with over 100K miles.

The car has been garaged for 11 years, and in the NOVA/DC area. So everything like hoses/wires, etc seem to be in about twice as good shape as my previous ungaraged cars. Also, I remember my 1983 Camaro in 1989 that had cracked interior dash and various quality-control issues that were so representative of US-made cars in the 80s. I would never keep those cars past 80-90k miles.

So with today's better made cars, I am so far going to keep the car longer. Of course, the engine could seize anytime if something breaks (even with the most diligent maintenance), but I plan to keep it for now as long as the hoses/non-metalic parts, etc structurally hold up well.
