Some vehicles are simply built for a lot more heavy duty use, and a lot longer service life. In some cases, to withstand some seriously rough conditions. I am partial to the Toyota branded Landcruiser, and to the 1998-2007 model years. The Lexus 470 is essentially identical, but with more creature comforts, and upscale appeal for the US market, the only market in which it's sold. It has tremendous paint, in nice metallic colors, softer, super high grade leather. More wood. More high grade stereo, and the air adjustable suspension.
We have a family friend who is a Toyota distributor, and owns a few stores. Back in the early 90's, we had just had our second Suburban literally fall apart at about 75K miles. We had bought it new, as we had the previous one. Both Chevy branded. Our friend said, "Just buy a Landcruiser, OK?" And he explained that there was no need to buy a new one, as I couldn't run it through a business, etc. That's when I began my education as to the genesis of the vehicle. It was build as high end exploration, or actually diplomatic vehicle.....with a service life of at least 500K. When Toyota determined that it had a lot of rugged appeal, they began to evolve the vehicle, and by 1998, it was pretty nice and plush in a rugged sort of way. They sold a lot of the Toyota branded vehicles, and began to sell and lease a huge number of Lexus 470's. Most of which have never been off road, many never in the snow.
That's a vehicle though that is build to handle whatever you can throw at it. For a long, long life. The engine has a lot of forged parts. Everything is built to be replaced as needed. The quality of everything is apparent. They were built in ONE factory in Japan, which was apparently whey all Toyota employees wanted to work. So, yes, they were "worth" the steep price. We have owned four. All bought used, and with anywhere from 40K to 100K on the clock. We sold our 80 to buy our first 100. We drove the 100 to 250K miles, and it ran like a stopwatch. We sold it because we got a line on an other mint, barely used, 2003. We put another 230K on that one, to about 260K. Then repeated, and bought another 2003.....because we tracked down a real unicorn in terms of color, and options.....no navigation, for example. We have owned that for six years, it has 140K on it, and it is amazing how many people think it is a new vehicle.
I've become really familiar with these vehicles, and do a lot of my own work, because I enjoy it. I make sure to keep on top of the fluids, the filters and belts. I have done other preventative work, like replacing all of the cooling hoses. That's about to happen on our current one. I drain and fill the alleged lifetime AT fluid. When I replace brake pads, I made sure to lube the guide pins in the calipers. We lube the drive shaft. I have an indie mechanic who knows the vehicles, too.
Bottom line is that these have proven to be incredible reliable, bullet proof vehicles in ANY kind of driving. I run Hakka snows in the winter on them. Goes anywhere, on any surface. The cost of operation and ownership is probably less than almost every car that we've owned.....and I think we have owned 50+ during our adult years. Our son has a Tacoma, 2002, with 250K+ miles on it. It looks and drives perfectly. He takes care of it, but doesn't baby it. He's modified the suspension, the frame, etc. He plans to own it for A LONG time. The material and build quality of that generation Tacoma is tremendous.
I agree 100% that not all Toyota products are the same....at all. A Sequoia is a neat vehicle, and it can also be a real value used. It's no Land Cruiser. I'm pretty familiar with them. Similarly a Highlander is not a 4Runner, and a new 4Runner is no "truck." We have a runner search going on in our family right now, and a new recent one is off the table.
Some vehicles just last longer, an are built for a different purpose. And some are just better built on any given day. We had an Audi S6 Avant, 1995.5, and we kept it for a LONG time. Last I knew, it was still a reliable daily driver, with 400K on it. Engine has never been rebuilt. Same turbo that we had on it 150K ago, original clutch.....
Sometimes you also just get lucky. I do agree that using a vehicle for what it was intended is also part of the picture.......
I really don't know how to advise the OP........
