Auto affordability is worsening
New‑vehicle affordability is getting worse not just from rates but because prices and dealer costs are rising — average transaction prices rose 3.5% year‑over‑year in March and dealers add material per‑unit costs like inventory carrying and make‑to‑stock inefficiency. The same dealer economics study says those channel costs can amount to as much as $5,000 per vehicle, and a recent tariff change now applies Section 232 to full customs value which can amplify short‑run cost volatility for importers and lenders.

A new car got harder to afford again in March even before the latest tariff change fully hit dealer lots. Kelley Blue Book said the average new-vehicle transaction price in March 2026 was 3.5% higher than a year earlier, with annual gains accelerating for a fourth straight month. (coxautoinc.com) That price growth was not just automakers slapping on bigger stickers. Cox Automotive said the mix shifted toward pricier full-size sport utility vehicles and pickup trucks while compact and subcompact cars kept losing share, so the average moved up because buyers bought more expensive shapes. (coxautoinc.com) Then there is the part buyers usually do not see on the window sticker. A new April 2026 dealer-economics study said state franchise rules force a dealer middle layer that adds roughly $3,934 to $4,992 per vehicle through inventory carrying costs, make-to-stock inefficiency, and duplicate retail overhead. (laweconcenter.org) Inventory carrying cost is basically interest on a car sitting still. If a dealer has to borrow money to keep dozens of unsold vehicles on the lot, that financing expense gets folded into the price the next buyer pays. (laweconcenter.org) Make-to-stock inefficiency is the other hidden bill. Instead of building one car for one named buyer, automakers ship batches to lots and dealers discount, swap, advertise, and hold them until the right customer appears, which adds storage, staffing, and mismatch costs. (laweconcenter.org) Now add a tariff rule that changed on April 6, 2026. Trade lawyers at KPMG and White & Case said Section 232 duties on covered steel, aluminum, and copper products now apply to the full customs value of the imported article, not just to the metal content listed on the invoice. (kpmg.com) (whitecase.com) That changes the math fast. If an imported part contains a modest amount of metal but a much higher total declared value because of electronics, design, or assembly work, the tariff base is now the whole package instead of the metal slice. (cassidylevy.com) White & Case said the April 6 rule also gives no exception for goods already in transit, which means importers can get hit by a different landed cost after the shipment is already on the water. Lenders and dealers hate that kind of surprise because floorplan loans, pricing sheets, and lease assumptions were built on the old number. (whitecase.com) The result is that affordability is being squeezed from three directions at once: buyers are choosing more expensive vehicles, the sales channel itself adds thousands of dollars, and tariff calculations just became more volatile for imported content. None of those pressures shows up as a simple interest-rate story. (coxautoinc.com) (laweconcenter.org) (kpmg.com) That is why a shopper can walk onto a lot in April 2026, see incentives still advertised, and still end up with a payment that feels wrong. The car itself costs more, the path between factory and driveway costs more, and the import-cost formula just got less predictable. (coxautoinc.com) (laweconcenter.org) (whitecase.com)
