Buying & Selling

When in the year cars cost less

Nobody can promise a cheaper car in a given month, and we won't put a percentage on it. What can be described is why some months lean one way: who is under pressure to sell, who is flush and ready to buy, and what is arriving on the lot.

Mechanisms tend to push sellers toward deals
Demand tends to be stronger, so sellers have less reason to bend
Mixed or neutral — the car and the lot matter more than the month

The shading is our reading of the mechanisms below, not a measurement. Tap a month to jump to its season. Everything that follows is a tendency — the kind of pressure that exists in a typical year — and any individual lot, model or local market can run against it. Weather, supply shortages and a single popular model can each override the calendar.

AUG · SEP · OCT

Changeover season

This is the season built around the model year. Many new models for the coming year arrive in late summer and fall, and when they do, the outgoing year's cars on the lot become the older version of something newer. Dealers have paid for that inventory, often with borrowed money that costs them for every day the car sits, so there is a reason to clear it. Manufacturers sometimes add incentives on outgoing models for the same reason. The timing isn't fixed: some models change over in spring, some mid-year, and some carry on with almost no change, which leaves little to clear.

For used cars, the effect arrives indirectly. New-car sales bring trade-ins, and trade-ins become used inventory. More supply on a used lot is rarely bad news for a buyer.

September also closes a calendar quarter, which brings in the next mechanism.

DEC · JAN

Year-end, and the quiet after it

December stacks three kinds of deadline on top of each other: the end of a month, a quarter and a year. Many dealerships and salespeople work toward sales targets, and some manufacturer programs pay out on volume reached by a deadline. A seller close to a target can have a reason to accept a thinner deal on the last few cars than they would in the middle of the month. How these targets are structured varies by dealership and brand, and you will never see the numbers — but you can see the calendar.

At the same time, December is when many households are spending on everything else, and in colder parts of the country it's not a month for strolling a lot. Fewer shoppers means less competition for a seller's attention. January inherits some of that quiet: holiday bills have landed, and foot traffic tends to be light until money starts arriving again.

FEB · MAR · APR

Refund season

Here the pressure reverses. Federal and state tax refunds arrive for many households in these months, and for a lot of people a refund is the largest single deposit of the year — exactly the size of a down payment on a used car. More buyers with cash in hand means sellers, especially at the lower end of the used market, have less reason to discount. You will often see lots advertising around refunds precisely because they know this.

Spring weather adds to it: people who put off shopping through winter come out. If you are shopping on a budget in these months, the counterweight is the same as always — be ready to walk away and to wait.

MAY · JUN · JUL

Early summer, mixed signals

Holiday sales events cluster around long weekends — late May, early July — and they do attract shoppers, which cuts both ways: advertised offers on one side, busy lots and less individual attention on the other. June closes the second quarter, adding a month-end-and-quarter-end nudge. Some new models start arriving in summer, starting the changeover early for those nameplates. Overall, no single force dominates. The specific car, and how long it has been sitting, will tell you more than the month.

NOV

November, between two seasons

The tail of changeover season meets the start of holiday spending. Promotional events around late-November shopping days are common, and outgoing-year inventory may still be on the lot. But household budgets are being pulled toward the holidays, and December's triple deadline is only weeks away — a patient buyer may do as well by waiting for it. We shade it mixed for that reason.

Mechanisms that ignore the calendar

Some pressures repeat every month rather than every year. The last days of any month carry a smaller version of the December effect for sellers who work toward monthly targets. Weekdays are generally quieter than weekends, which buys you more of a salesperson's time and less of a crowd. And seasonal demand for particular kinds of car follows the weather: convertibles tend to be easier to buy when it's cold, four-wheel-drive vehicles when it isn't — the reverse of when most people want them.

Then there is the calendar that matters most: your own. A lease ending, a registration renewal, a car that's failing — each sets a deadline that can outweigh anything on the wheel. The best seasonal strategy is often simply to start early enough that you're never shopping under your own deadline. If you are trading a car in, when to trade in covers the timing from the other side. And whatever month you buy in, the out-the-door price is still the number to negotiate; a seasonal discount that comes back as fees isn't a discount.

One last caution about year-end ads specifically. A "sales event" is a marketing device first. It can coincide with real pressure on the seller, or it can just be a banner. Year-end sales events: what they're worth reads the typical claims line by line — worth a look before December, when the wheel says the timing is on your side and the advertising says so too, loudly.
