2018 Kia Sorento vs 2018 Toyota 4Runner
Two midsize SUVs, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2018 Kia
Sorento
6/10
Buy it for the V6 with a documented Theta II settlement claim already paid — everything else about this generation is genuinely good.
VS
2018 Toyota
4Runner
8/10
Slow, thirsty, and cheaply finished inside, but it will outlive you and hold value like a Rolex.
Milo scores the 2018 Toyota 4Runner higher — 8/10 against 6/10.
