2018 Chevrolet Silverado 1500 — Should You Buy One?

Kestrel Take

The last year of the K2XX Silverado — a proven, straightforward truck with the familiar AFM lifter caveat on the 5.3L. The 6.2L is the enthusiast engine; the 4.3L V6 is a durable base option. Check for lifter tick, transmission shudder, and the cracked dash.
