2018 Chevrolet Colorado ZR2 — Should You Buy One?

Kestrel Take
A genuinely serious off-road midsize — the ZR2's front and rear locking diffs, trick Multimatic DSSV dampers, and wider track make it a Raptor-lite for the trail. That capability means many were wheeled hard, so inspect closely. Verify the 8-speed fluid service and, on diesels, emissions upkeep. A clean, un-abused ZR2 is a hugely capable and desirable truck that holds value well.
