One thousand eighty dollars, six months, and a 12-by-25 unit in Bloomington with a thermostat holding 55 degrees. Apr 6, 8:05 in the morning, 41 degrees outside, and I am rolling up a corrugated steel door to find out whether a winter of $180-a-month rent kept a 23-year-old Trans Am alive. Sta-Bil and dryer sheets hit me first, which is the smell I left there in October. The battery tender's light was green. The car sat level on four plywood squares, tires still round, paint still holding the wax.

The winter before, the car spent November through March in my driveway under an $89 car cover, and that arrangement cost $680 after the fact: $430 for a detail shop to extract a mouse nest from the HVAC box, $85 for the blower resistor the mice had chewed through, $165 for a battery that January killed past recovery. The cover came off to sunflower seeds. The nest was built from HVAC insulation and seeds the birds never got. My mechanic said he pulls at least four of those nests out every spring.

The unit was never the part that mattered, and the item I trusted most on the whole checklist cost $12: a bottle of fuel stabilizer, cuz the prep list is the difference between a car that wakes up in April and a car that wakes up angry. Nine steps. One Saturday. Step six, the steel wool in the exhaust tips, is the one I would defend in court.

the driveway winter, $680 of mice

Here is the itemized receipt from the free parking spot. HVAC nest extraction and duct sanitizing: $430. Blower resistor and connector: $85. New battery, because the old one sat thru three nights at minus 14: $165. Total: $680, plus two weekends of my own labor and a smell in the vents that never fully left. A driveway costs nothin' monthly and everything in April.

unit 114, thermostat at 55

I called three facilities on Oct 2. Outdoor uncovered: $165 a month. Climate-controlled drive-up: $180. Premium insulated interior: $240. I took unit 114, a 12-by-25 with a wall thermostat I set at 55, because the car is 16.8 feet long and I wanted walking room at both bumpers. The manager wrote the temperature rule on my lease copy. Stable beats warm; the enemy is the swing, not the cold.

nine steps, one Saturday

The whole prep fit into one Saturday, Oct 14. Wash and wax, $0 and four hours of my own arms. Fresh oil and filter, $62, cuz old oil sits with acids in it all winter. Tank filled and treated with Sta-Bil at storage concentration, $12. NOCO Genius 2D tender on the battery, $45, extension cord run to the unit's outlet. Tires at 42 psi on four plywood squares. Steel wool in both exhaust tips, dryer sheets in the cabin. Fluids topped, parking brake off, wheels chocked, $16 for the chocks. Wipers lifted off the glass. Breathable cotton cover, $89. Supplies: $224.

step six, steel wool in the tips

The mouse that ate my HVAC came in somewhere, and every storage veteran I asked pointed at the same front door: the exhaust pipes. A fist of steel wool in each tip blocks it without rusting into the pipe the way crumpled foil can, and it costs six dollars for a bag that could stuff twelve cars. The dryer sheets are the folk remedy half of the equation. I use them cuz the one winter I did, nothing nested. That is my whole dataset and I am sticking to it.

the $45 tender and its green light

The tender's logic is simple: hold the battery at float, never cook it, and report with one amber light while charging and one green light when holding. I checked it once a month on a Tuesday, typically on the way home from the gym. Green every visit. The battery that died in the driveway winter was $165; this one has now survived two winters and reads 12.6 volts on the first meter touch every April.

month three, a Tuesday visit

Jan 14, 9 degrees, and I stood in unit 114 for six minutes in my gym coat. Green light, no droppings, no seeds, tires unchanged, dryer sheets still spread across the seats like terrible potpourri. I did not start it. A five-minute idle charges nothing and condenses water into the crankcase, and everyone with an opinion falls on one side or the other of that question. Either drive it 20 miles or leave it alone. I left it alone.

first start, second crank

Apr 6, and the sequence took eleven minutes. Steel wool out of both tips, bagged and into the glovebox ziplock. Tender off, cables coiled. Tires bled from 42 back down to 32 psi. First crank: slow, no catch. Second crank: fired, idle at 1,100 rpm, settling to 750 inside 40 seconds. Brake pedal firm on the second pump. Two miles around the facility roads, wash at the self-serve bay for $4, then 61 honest highway miles that weekend with the windows down.

both columns, side by side

Driveway column: $0 rent, $430 nest, $85 resistor, $165 battery. Total $680, plus a smell that outlasted the receipts. Unit column: $1,080 rent, $224 supplies, $0 damage, $4 car wash. Total $1,304. The delta is $624, or $104 a month, and it buys zero mice, round tires, and a green light at every Tuesday visit. For a car I am keeping until somebody pries the keys loose, that math holds. For my beater F-150, the driveway wins, with a $6 bag of steel wool jammed in the exhaust.

The door rolled up at 8:05 and the car looked the way October left it, which is the entire product I paid for. The receipt stack reads $1,080 rent, $224 supplies, zero mice, second-crank start. I booked unit 114 again on Oct 1 before the waiting list did. The steel wool is back in the glovebox, ziplock and all, waiting for the first frost.
