Iowa winters and the salt-belt cycle
Iowa runs the salt-belt wear cycle that defines junk-car economics across most of the Northeast and Midwest. Heavy December-through-March road salt eats body panels, brake lines, and undercarriage hardware. By year 8 most Iowa cars show visible undercarriage rust; by year 10-12 the brake-line and frame-rot situation typically pushes a repair-vs-junk decision.
Sub-freezing January cold-starts compound the wear. Battery life drops from a typical 5 years to 2-3, oil thickens, rubber components stiffen and split, and engine blocks crack on the worst cold snaps. Working trucks often outlast sedans on the powertrain side because their drivetrains are built for it; their bodies, however, take the same beating.
Across our Iowa pickup history, the dominant junk-out pattern is body-driven, not engine-driven. Most cars we buy here run, sort of, but the rust math no longer works.
Working-fleet mileage and the Iowa truck market
Iowa fleets stretch service life longer than coastal averages. F-150s, Silverados, Rams, and older domestic SUVs with 200,000+ miles aren't unusual. Frame condition and drivetrain status drive the offer more than the odometer reading — we don't penalize for high mileage on Iowa pickups.
Catalytic-converter theft hit the salt-belt hard from 2021 through 2023. Documented cores remain valuable; cars with stolen cats see offer drops in the $300-$500 range. We still buy them — the cat is one component of the whole-car value, not all of it.
