 I have owned my 98 Tacoma for nearly a decade now. The truck is running 238k miles and the last California smog it had last year, it passed with flying colors. The mechanic was not surprised in the least that with all of the regular normal maintenance I do, that the Tacoma was still passing smog like it had at 5k miles. 
 In the entire time I have owned my Tacoma, I have only replaced the battery once, the water pump and radiator at 220k miles and the alternator at 200k miles. I use only genuine Toyota parts. This truck has hauled boats, motorcycles, sand, cement, u-hauls and still sparkles like the day it came out of the factory and has not lost any power over the years. Solid truck!
