Take a look at almost any "What vehicles will go 200K plus" list. Every one has Land Cruisers and Suburban/Yukon/Silverados on them. IMHO, American vehicles aren't as bas as they used to be and the Japanese ones aren't as good.
I think that's very fair and accurate, too. I do know, well, that the mid 90's Suburbans were hit and miss, and I had heard that from friends who were dealers. What never made sense to me was that the GMC's seemed to last longer, and in almost every sense be better vehicles, than the Chevy with the bowtie on the grill. One of those friends is both a Chevy and GMC dealer and he felt the same, though had no good answers.
Right now, present time, I know a lot of people driving that platform, often with a lot of miles. I have friend who runs one through his business, then passes it to his wife as soon as his finance guy says to, then she passes the one that she had been driving to one of their sons. Right now, there are five in the family. So, yes, like many vehicles, taken care of and maintained, they are easily good for 200K+ miles.
And Japanese cars not being the ultra reliable things that they were. With the exception of some Toyota trucks...AND THE LC....I tend to agree. We have a number of friends whose kids are driving around town in first and second generation Hylanders. They look almost new, and they go and go. 300-400K. My 60 year old sister in law has never had anything but a Honda, and she is "not great with cars." The old ones just went on and on. The newer ones need to be taken care of. Even her last two Pilots.
One of the best most durable bullet proof cars that we had in our family was a 2002 Subaru Outback H-6 with VDC. Man, it ran like a sewing machine. Till the subframe rusted out. Two of the absolute most expensive and "needy" were a 2005 Legacy GT wagon, and a 2007 Outback 3.0. Great looking cars, and awesome in snow, but wow....expensive to maintain. Maybe we were unlucky.
We are just two of those strange people who love our Landcruiser{s}. Long term relationships. And the soul.....
Our son has a Tacoma with 300K+ on the clock. The thing is amazing. Original clutch. He's taken good care of it, and will own it, maybe as a third or fourth vehicle, forever. In looking at new trucks, would he buy a Tacoma or a Tundra? No, it will be an American Truck. No question. And probably a diesel to drive 500K miles.
Like skis, lots of good vehicles out there!
