New or used in 2026? An honest math walkthrough from our finance desk

The honest answer to "should I buy new or used?" is the least satisfying sentence in this business: it depends on the spread. The spread (the gap between the new price and the 2-to-3-year-old used price of the same model) has moved around wildly these past few years, and in 2026 it looks different again. Let me show you how I actually run the numbers at my desk, with a worked example you can redo for any vehicle on our lot.

The three numbers that decide it

Ignore the sticker for a moment. The comparison that matters is: (1) the rate gap, since new-vehicle financing often runs two to three points cheaper than used; (2) the spread, meaning how much of the price the first owner already absorbed in depreciation; and (3) the warranty runway, meaning how many repair-risk years you're buying either way.

A worked example from our own lot

Take a compact SUV we sell in both flavours. New, it's about $46,000 at 5.49% over 72 months. The same model three years old with 45,000 km is about $36,000, but at 6.99%, the used-vehicle rate. Run the amortization (our calculator does this in ten seconds) and the used one still costs roughly $160 less per month, and about $9,000 less in total. The rate gap narrows the spread. It doesn't erase it.

So used wins? Usually, yes, if the spread is real. And that's the 2026 catch: on the most in-demand hybrids, three-year-old examples are selling within 10 to 12% of new. Pay near-new money at a used-money rate, minus half the warranty, and the math quietly flips.

When new is genuinely the right call

• The spread is under ~15%. Popular hybrids and some trucks fall here right now. You're paying a small premium for a full warranty, first-owner history and a cheaper rate.
• You keep vehicles 8+ years. Depreciation is a first-three-years problem. If you drive it to 250,000 km, you'll own it long past the part of the curve that hurts, and the warranty runway matters more.
• A promotional rate is on the table. When a new-vehicle rate offer undercuts used rates by about three points, run both scenarios before assuming used wins. Read the terms, too: most promotional rates are on approved credit and shorter terms.

When used is clearly the right call

• The spread is 20%+. Sedans, minivans and larger gas SUVs mostly still depreciate the old-fashioned way. Someone else paid the steep part of the curve, so say thank you.
• Your budget is payment-driven. A 2-to-4-year-old vehicle at a shorter term usually beats a new one stretched to 96 months. Long terms feel cheaper monthly but you're underwater on the loan for years.
• You want more equipment per dollar. Three model years buys you a trim level or two. Heated everything for the price of cloth seats.

The two mistakes I see weekly

Mistake one: shopping the payment, not the term. A $299 bi-weekly payment over 96 months is not cheaper than $340 over 72. It's about $4,000 more expensive and traps you in negative equity until year five. Always compare total cost; the calculator shows it on every run.

Mistake two: valuing the warranty at zero. A used car with 18 months of factory coverage left and one with none are not the same car at the same price. One out-of-warranty hybrid battery or infotainment module can erase years of "savings."

Do this before you visit any dealer, including us

Pick your model, price it new and 3 years old, and run both through an amortization calculator at realistic rates. Five minutes of math turns you into the customer who can't be steered, which frankly makes my job easier too. If you want a second set of eyes on the numbers, get pre-approved and I'll walk you through both scenarios side by side, no commitment.
