Interesting bit of info to share
I was reading an issue of Corvette Magazine today, the subject was the 2019 ZR1. There was an interesting line, a quote actually from one of the Chevy folks. He said that the lifespan of the 755 hp engine was 100,000 miles.
Now to relate that back to our C4's. There are multitudes of cars well north of 100,000 and multitudes getting close. The value of our cars would really drop if they were a 100 and done, needing the engine rebuilt (in this case they were talking about the bearings and the designed for 100,000 mile lifespan). Since the advent of fuel injection and better controls I have taken a couple cars to all but 200,000 miles and it was other stuff that wore out. With the proper maintenance a modern engine should do 200,000 easily.
While the newer cars are cool and light years ahead of ours in technology, the newer ones are going to be iffy, much more iffy to own than a C4 is due to the problems that are manifesting themselves and projected lesser life. Another example is (I believe it is the C6's) and the stuck shifter. In the letters to the editor, folks have been writing in about that problem (pretty common from the answer back) and the expense to fix it.
Just sharing and starting out a conversation thread with other C4 owners...... which is what this forum is about.

Judging by the cost of the new ZR1, it will be a long time before we see many with anywhere near that many miles.

It was a quote from Tadge Juechter, Corvette Magazine April 2018 issue, page 33, bottom right hand corner. Tell him you don't think so.
He was discussing bearings. If they know that 100,000 is an issue, then when the cars are in the real world environment, with real world differences in those engine bearings, we should expect to see some premature failures.
As far as the cost, it only affects the ones of us that think that kind of money is a lot. I took care of a trust system for big money trusts and there are lots of folks, and lots of folks living on daddy's or grandpa's money that a bit over $100,000 is pocket change. To them it is a driver so they can not drive the Ferrari or Lambo as much.

I think a lot would also depend on how hard you push the engine...I haven't seen the quote, but I'm guessing his comment was made on duty testing of parts under extreme conditions where the ZR1 owners are pushing the engine frequently such as week road course racing and/or dragging.
But as others said too, most of those cars will barely see 10K put on the clock, let alone 100K!

This is especially true of the rocket surgeons who might buy one of these as an "investment" and leave them in bubble wrap for the next 25 years.

x2 most owners dont even drive them...still, 100k is good for a blower car period
Think owners expect way too much. They want a big # bragging rights, has to be quiet and comfortable as a caddy and get 40mpg.
Planned obsolence, too much electronics in those cars whos gonna care in 20 yrs? Look at most C5s cant give em away they got so many gremlins. Whats the use?

Out of curiosity I went out to autotrader and took a look at cars on the market just a couple years old. You can tell that a lot of people probably lease them and turn them back in with 25K or so miles on the car.
I found it interesting to see him say in print about the anticipated lifespan. And yes I agree that all these new, high horsepower cars are approaching the limits. It is one thing to have a supercharged/turbocharged engine that get torn down and rebuilt often another to have cars lose their resale value due to planned obsolescence.
Around here, C5 prices are often less than the asking prices for C4's.
