For the life of me I can't figure out why someone would drop almost 10k on a vehicle with 150k on it. Why not buy something low mileage like a Honda civic or something for the same price? A 4runner will run a long time but at that mileage a good portion of its usable trouble free life is gone.
I just bought an 05 Sport V6 4wd with $150K miles a few months ago for around $10K. Had maintenance records for the last 100K miles, engine is strong, transmission smooth, 4wd works great, no rust underneath, so I wasn't concerned about the mileage.
There are a lot of folks on this board with 250K+ miles on their T4R, heck even one with around 450K miles!
With the proper maintenance I am doing, I'm not all that concerned with it lasting another 150K.
