Two midsize SUVs, compared on what actually matters when you're buying used: what breaks, when it breaks, and what it costs you.

2018 GMC
Acadia
5/10
Great space and ride for the money, but budget for a shift-module fight and a timing chain gamble on the V6.
VS
2018 Toyota
4Runner
8/10
Slow, thirsty, and cheaply finished inside, but it will outlive you and hold value like a Rolex.

If you buy one, buy this one

✅ 2018 GMC Acadia

2018 Acadia SLT or SLT-2 with the 3.6L V6 and AWD — confirm both recalls (shifter/software and driveshaft) were performed, and get a pre-purchase transmission fluid/timing chain inspection. This spec gives you the power and features without overpaying for Denali badge equity.

✅ 2018 Toyota 4Runner

2018 4Runner TRD Off-Road Premium (4WD) with KDSS — the sweet spot of off-road hardware, reasonable ride quality, and a manageable price versus the TRD Pro premium.
