My dad had a 90' T4R with about 390k miles until someone hit him on the side in 2001'ish. His 83' Cressida had even more miles until he struck a dog in the middle of night. His 07' Tacoma has 243k+ now
My 02 has 134,300 on it. My grandpa's 98 is a few hundred away from 350,000 and my dad's 02 is right around 195,000. My old 2nd gen 95 had 239,000 when I sold it.
My 2005 4runner sport has 270,000 miles. I use it to haul my 2000lb cargo trailer for work everyday for the last 2 years and it still runs great. I just make sure to put the trans into 4th gear when hauling.
When the vehicle was under warranty It was taken to the dealership for scheduled maintenance. Now I do the maintenance myself and make sure to change the oil every 5000 miles with good high mileage oil. At 200k I flushed transmission, differential, break, power steering, radiator fluid. I plan to flush all fluids again at 300k.
