I bought a 2019 Limited last year. I looked around on cars.com and ultimately found one with 34,000 miles for $38,000. I am extremely happy with it. I must be getting soft in my old age, but I love the heated and air conditioned seats.
Compared to my 2007 SR5, the handling of the 2019 Limited is night and day, which I assume is largely due to the XREAS suspension. If/when mine fails, I will probably pay whatever it costs to get it repaired.
I did find the ride a bit rough. The ultra low profile tires made every little bump feel like it was shaking the car apart. I switched to 18" wheels and 265/65-18 tires and that took care of the problem. If you are interested, you can see the details and pictures at the following link.
Wheels - Raceline or Black Rhino
One thing to look for on 4Runners is frame rust. I had to have a frame/welding shop repair the cross member and mounting brackets for the rear suspension on my 2007, which was not cheap. So I was super picky when looking for this one. I actually flew from Cincinnati, Ohio to Manassas, Virginia to buy it.
