Scotty Kilmer's favorite car claims they run 3 or 400,000 with out a problem if you keep them serviced. I have owned several Toyotas and never had to have one of them repaired other than tires and battery. I have a new Highlander but prefer my 2001 Ford expedition, personally but wife like the Highlander it does have some cool features and comes with 10 year 100 thousand mile bumper to bumper warranty, since I am 83 I won't ever have to repair anything on it never even looked under the hood or anything else. My Ford will likely outlive me without a warranty.
My wife has ‘recycled’ two highlanders to her daughter. She returned the first but still Hass the 2005.
The daughter’s husband drove a Rav-4 for over 20 years.
When you get in your 80’s vehicles like yours and ours may cost a few bucks every other year.
Like you said when you are at our age, those well built vehicles when taken care of, could outlast us.
Before, I bought my Honda Ridgeline, I talked to many neighbors with Honda’s and most were in the 200,000 miles range with basically just normal upkeep and tires. That was close to a decade and many of those vehicles are still running.
One family has had 4 kids in college at once and 2 old Honda’s have been out there with the kids and and still are running.
