You really expect to own one of these 20 years in?

I don't disagree with you on the benefits of changing the differential oil prior to 20 years, but I just wonder how relevent it will be.

I had a 1990 Q45 with 245k when I sold it.

Computerized. ECU, ABS, bus-linked modules, all the bells and whistles that the BMW has (no nav)... I still see it around, it is still on the road- now 20 years later.

I have a 2001 MDX. Computer. All the above plus more. 207lk, kids beater- but every single module works.

I have every expectation these car will indeed last. I do not expect software updates, but why would you want/need any??? After 5-10 years the software is stable, no need for new code. If you lose a module, head to ebay or a junk yard for a replacement. Indeed, given the numbers of units made, I really don't expect cars being junked due to 'lack of electronic gizmos'

For the last 20 years people have been bemoaning the advent of "these newfangled computer based control systems will mean the end of [DIYers, lifetimes over 10 years, etc]" and it just hasn't happened.

Now, what really happens is (a) people tire of getting screwed over by dealerships and would rather have a monthly payment, (b) most people have no clue how to use a screwdriver, (c) consumers use failures as an excuse to buy new- they don't want to be seen in 'old cars'

Dunno if I'll be owing and driving the X in 10 years when it hits 200,000 miles- but I am figuring I will 'pay it forward' for them with my maintenance. SOMEBODY will benefit from it.
