Your Trip Data Already Knows Which Cars Won't Survive the Winter

Fall and winter, outside the holidays, is Turo's documented slow season. A car you're eventually going to sell is worth more sold in October than in February -- you skip months of near-zero earnings while insurance, parking, and depreciation keep running. Here's how to tell which cars in your fleet are actually winter-proof, using data you already have.

Why the year-round framework isn't enough

The utilization framework tells you whether a car earns its keep across the whole year -- but an annual average can hide a seasonal cliff entirely. A convertible or sports car can post a perfectly healthy annual utilization number that's really just a great June through August and nothing else. This is about the time dimension that number hides.

Three seasonal signals, built from data you already have

1. Shoulder-month decay rate

Compare September-October booked days against the same car's June-August. Some drop is just the season -- but a car falling two or three times faster than your fleet average is telling you winter renters specifically don't want it.

2. Last winter's floor

For any car you've held through a previous winter, pull November-February utilization and revenue-per-available-day from last year. A car that ran at a third or less of its summer utilization last winter, with no market changes since, will very likely do it again.

3. Winter earnings-per-mile squeeze

Winter trips tend to run shorter and more local, while fixed costs don't shrink to match. Recompute earnings per mile on a winter-only date range -- cars that were marginal in the annual number often go negative once you isolate winter.

Know your market's seasonality -- it isn't universal

Snowbird markets like Florida and Arizona often peak in winter rather than dipping. Ski markets reward AWD and SUVs specifically. Northern urban markets tend to see the steepest across-the-board drops. Use your own fleet's trailing data for your actual market, not generic national seasonal advice.

The decision rule

• Strong summer, dead winter, car holds resale value: consider selling in fall and rebuying in spring, or a planned seasonal snooze.
• Weak summer AND dead winter: this is the sell-it rule from the utilization framework, now with a deadline attached.
• Decent winter floor: keep it, and run the slow season playbook instead of selling.

Pulling the data

Export per-vehicle P&L entries and GPS mileage by date range for each window -- summer, shoulder season, last winter -- and build the comparison directly. MooveTrax doesn't calculate seasonal utilization for you; see how the P&L and mileage export works as the raw material.
