Why buying a used truck is a harder bet in the IE than almost anywhere else

Citrus Belt Review: Used Class 8 prices have held about flat — up 0.8% over the past year per J.D. Power — with fewer trucks selling and lots aging. In a normal year that soft market would make now a fine time to buy.

But starting with the 2027 model year, the EPA makes new heavy-truck engines cut smog-forming NOx by 82 to 90%, and new trucks built to it were projected to run $20,000–$25,000 more. That normally triggers a "pre-buy" — a rush for cheaper pre-2027 diesels that drives up used prices.

The rush mostly hasn't come. The EPA has confirmed it's keeping the 2027 deadline and the standard — but a proposal expected this spring would ease the warranty and engine-life rules behind much of the cost, which could pull the premium down toward $15,000 a truck. So the date is locked while the price tag isn't, and the expected buying surge turned into wait-and-see. The result: the number that matters most — what a 2027 truck actually costs — won't be clear until the proposal lands, which makes pricing a used one today a guess.

For an IE operator, California doubles the fog. The state rules meant to push diesel out of port drayage are themselves up in the air — CARB pulled its enforcement request on the drayage piece of its Advanced Clean Fleets rule, and related rules are tied up in court. A trucker in Texas weighs one unknown, the federal cost. An IE trucker weighs that plus a state electric-truck mandate that may or may not survive — more trucks, more rules, less room to be wrong.
