what is "high mileage" on a modern car?
 
just curious.

130,000mi on the E61 now. it's pretty expensive to maintain (replace failed sensors and ageing parts) but there isn't really anything else on the market like it.

vacillate between keeping the E61 until 150,000mi or selling it.

the fact is: I don't know what will be looming in terms of major issues for the engine. the transmission and all wheel drive system fluids get changed every 50,000 miles so if they fail, that's just fate.

Good question. Is there such a thing so long as you are willing to maintain everything(?) If the engine or transmission go, is the cost to repair/replace really unreasonable if the car is still otherwise desirable?

I would be curious to see a compression test between your engine and a newer one. Might even make sense to start doing Blackstone analysis on the oil changes to watch for abnormalities.

I'm just under 85k miles on the Tesla. Other than a couple minor dings and small scratches/rock chips, its hanging in there well. No rattles and everything works, although the battery is showing a little degradation (about 9-10%).

Main warranty has another 15k miles on it (or just over 3 years…), and the powertrain/battery warranty has another 35k miles / 3+ years. I won't be keeping it out of warranty though -- while nothing major has needed replacing recently, it did have a lot of warranty work when it was new (including a drive unit, which was common for early Model S). But if the MCU (main screen) fails, that's a ~$4k repair...

I still consider the high mileage point between 100 and 120k based on my experience of when lots of things start breaking. It does seem like if you get past 125k you've fixed most things and should have another shorter period of time of infrequent big ticket items.

on the N54, it was the turbos (that failed and I replaced), the electric waterpump (that is buried to the cost of $1000 in labor to get to) and injectors (that on mine were starting to leak a little and would have been the next thing for me to replace) that were the high dollar concerns. Cheaper but still in need of address is carbon build up, HPFP possibilities, the wiring in the trunk lid to the diversity antenna (mine failed) and CCC I drive issues (I had to replace my controller) and of course the risk of catastrophic failure from sunroof leaks.

I also started having severe CV joint vibrations after about 100 miles of driving that would have required a new front axle. Had we not traded it the weekend we did.

I assume you've seen the PDF of e60 ownership issues here:

Funny though, even after all the above my wife still hates the X5 (which has been bulletproof) and misses the wagon a lot.

Have you seen the new V60. It looks like a great pacakge on paper, especially if they bring the T8 power train over here.

We kept the e39 528i to about 130k. In retrospect, it was stupid to sell that car for around $5k. Beautiful color, solid, and only minor things going. It wasn't free to maintain, but it had no high dollar failures to that age.

I’m starting to ask myself the same question as my N54 starts approaching 100k miles. I’ve done the water pump, but not turbos or injectors or carbon cleaning or anything else, really, other than fluids, brakes, and tires. I kind of wish I was starting to get sick of the car but I’m not. But I know there’s got to be some pricey stuff not too far off on the horizon and wonder if I’ll regret not cashing out before that happens.

You're in a unique position of having a car that is appreciating in value. I'd think if you kept it maintained you'd be able to get most of your investment back if/when you do decide to sell it.

Depreciating more slowly perhaps, but I don’t think it’s actually appreciating, is it? But point taken. It ain’t no garage queen though, it’s living a daily driver life.

So I expect the turbos to go. Soon-ish.

The water pump was done at 72k miles.

I paid out of pocket for walnut shell blasting of the valves.

The HPFPs were both replaced eons ago —which means they’ll come back as well as injectors.

I have the water drainage tubes blown out every year.

But this still leaves the IBC (intelligent battery cable) as an issue. The rear air suspension.

I don’t know. It still runs well.....that’s why I thought I’d ask. Appreciate all of the thoughts thus far, guys.

I am not a good person to ask... lol

1994 Explorer - sold @ 180k
1973 2002 - sold @ 235k (but then again - I had it 28 years)
1995 740i - sold @ 210k (really only sold it as I had a second E38 already)
1983 300SD - sold @ 270k (wish I still had it)
1987 420SEL - sold @ 240k (almost wish I still had it)

Have not sold but will donate 2001 Yukon @ 290k. Yes, almost 300k on the clock.
Will not die... Ummm... Now that I may have the room... Ummm.... oh snap. yeah -Donate!

I must have a golden touch. None of the cars I have disposed of had given me any trouble at all - I just move them out as I get nervous that they 'might' give me trouble.
The buyer of the 300SD contacted me a few years after I sold it to him and let me know the car had about 400k on it by then (and he wanted to know when I was going to sell him his next car - lol)
