What a Quick Walk-Around at the Auction Yard Can't Tell You
A quick yard walk-around can't show how a car runs, its frame, flood damage, or wiring. Here's what to check before you bid.

The K2-generation Silverado 1500 is one of the most common trucks at salvage auctions. The known problems to price in before you bid: AFM lifters, the 8-speed shudder, AC condensers and more.
The 2014–2018 Chevy Silverado 1500 (and its twin, the GMC Sierra 1500) is everywhere at Copart and IAA. That's good news for a flipper: lots of supply, lots of parts, and buyers who want them fixed. But this generation has a few well-known problems, and if you don't price them in, a "cheap" truck stops being cheap.
You usually can't drive an auction truck, so you're buying on what you can see, hear and research. Here's what to look for.
Active Fuel Management shuts off half the cylinders to save fuel. The special lifters that make that happen are this generation's best-known weak spot, especially on 2014 trucks.
Trucks with the 8-speed automatic often developed a shudder that feels like driving over rumble strips, caused by the torque converter clutch and the original fluid.
The 6-speed trucks are generally the safer bet.
Weak or no AC from a leaking condenser was a common complaint around 50,000–70,000 miles. It's not a deal-breaker, but on a front-end hit you'll likely be replacing the condenser anyway.
Front-end damage is the most common listing. On these trucks a front hit can include the radiator support, condenser, radiator, headlights, bumper, grille, hood and fenders, plus airbags and sensors if they deployed. Look for:
Find out what the truck is worth fixed in your market (same trim, cab, bed, 2WD/4WD, mileage). Subtract: parts for the visible damage, a lifter-job reserve on any V8 that ticks, a transmission flush reserve on 8-speeds, buyer and gate fees, transport, and your profit. That's your maximum bid. See Copart vs. IAA for fees.
This generation is still one of the best trucks to flip. Just bid like you already know about its problems, because the other bidders do.
