I don't understand this part. What published expectation is 200k? Aside from that, I've never had a vehicle that hasn't gone 250k reasonably trouble free miles.
It popped up in a query from a reliable site, but I don't remember exactly where it was. that's what I saw "in print". It's a statistical expectation, and if accurate, is below what one might expect if the vehicle hasn't been abused. In fact, for other reasons, it could be lower than the average, but let's say it's an average. That's because the quality control estimation is equivalent to an average with a tail on the distribution, so you might expect more. A warranty-supporting estimation would be far lower than the average. I also know what you are saying about more modern vehicles and their engines. I met a guy in 2020 with a
beautiful red-white two-tone 75 Chevy Blazer, and I asked him about engines and mileage: "500,000 and four engines". That was the old days. With vehicles newer than that Blazer, you can expect more. But you cannot circumvent or defeat eventual metal fatigue.
If I had a friend who kept a 66 Karman Ghia running for 57 years, I could also see overhauling the Pooper's engine after hopefully many more trouble-free miles. [She got $16,000 for that thing, too.] I could do anything I want. I could call the junk yard and a tow-truck, but my friend who owns the repair shop told me "Somebody will buy it!" Who knows?
Finding parts for an orphaned vehicle has been much easier than the myth I'd heard from this or that mechanic. There's even an Isuzu Warehouse in Washington State and another one in Missouri. They have every single part and part number listed for a 1995 Trooper LS, and "Add to Cart" buttons. More often than not, they return a message that "this part is no longer available", but for parts I've sought which could only be OEM, they've turned up new stock in Japanese warehouses and I acquired them. First, the 12-CD Changer I obtained (2020) for $90 new in the original Isuzu carton, and then a front bumper part known as a "back-bar" (2021) for $125 -- an S-shaped item that attaches to the frame, two of them holding the metal bumper and the vinyl piece that people see.
This has all been quite an education for me in my experiment to take a used car to 31 years of reliable road travel. I want to say that the experiment has been reasonably successful.
For after-market, I'd originally noted that there was a grille-guard or "bull-bars" you could get for the Trooper back in 2005, and I thought for the price I would forego it. It reminds you have the same sort of assembly you find on Ford Explorer police vehicles. I happened to find one in stock with a company up in Bakersfield for half the '05 price when I bought it in 2019.
So you can see how my attachment to the vehicle had gradually grown, selecting and installing enhancements, like a rocker-switch with USB ports, an MP3 player and an Android tablet mounted to the dashboard. I added fog lights to the grille guard. I could put up my photos of these projects, and I guess I was planning eventually to put a picture of the vehicle in a link or insert here.
I have to call this "a hobby". While I believe in application of capital-budgeting logic regarding the possession, maintenance, salvage and replacement of cars, "Hobby" is a significantly different dimension to my ownership and experience with this SUV.
