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 — new-vehicle financing typically runs two to three points cheaper than used; (2) the spread — how much of the price the first owner already absorbed in depreciation; and (3) the warranty runway — 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 10–12% 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 subvented rate is on the table. When a manufacturer offer (like this month's 3.99% on new hybrids) undercuts used rates by three points, run both scenarios before assuming used wins.

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 — 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.
