How to Store a Classic Car in Arizona’s Desert Heat

Lake Havasu is one of the best places in the country to own a classic car, with a winter car scene that draws hundreds of entries, and one of the hardest places to store one through the summer. From May to October the sun, heat and dust work on a parked car every day. Here’s how to store one so it comes out in October the way it went in.

What the desert does

Sun. UV fades paint and chalks single-stage finishes, cracks dashes, dries and splits vinyl and leather, and ages rubber (tires, weatherstrip, hoses, belts) on the calendar rather than the odometer. A tire that looks fine can be too old to trust; read the DOT date code, and treat a tire more than five years old as a replacement conversation regardless of tread.

Heat. Cabin temperatures in a closed car in full sun run well past what interiors and electronics were built for. Lead-acid batteries lose years of life in Havasu heat; fuel evaporates and goes stale faster; old wiring insulation gets brittle.

Dust. Fine alkaline desert dust gets into everything, abrades paint under a loose cover, and packs into brakes, carburetors and ventilation.

Covered, indoor, or outdoor

Indoor, climate-controlled is the gold standard for a car with real value, and the best choice for an original interior or a show finish. Indoor, not climate-controlled (a garage or a storage unit) solves sun and dust and most of the heat. Covered outdoor stops the direct UV but not the heat or dust. Outdoor under a car cover is the last resort: use a breathable, soft-lined cover made for the car, never a plastic tarp, and wash the car before covering it so the cover isn’t grinding dust into the paint. Covered and indoor storage in Havasu carries a premium; ask what’s available before you commit to a summer here.

The storage checklist

  • Wash, dry and wax before storage; the wax is the UV barrier.
  • Fuel: fill the tank to limit condensation, add a stabilizer rated for the storage length, and run it long enough to get treated fuel through the carburetor or injectors.
  • Battery: on a maintainer or disconnected and stored cool; heat is what kills it.
  • Tires: follow the tire and vehicle manufacturer’s guidance on storage pressure and on whether to take the weight off the tires for a long summer; flat-spotting is the risk.
  • Fluids: fresh oil before storage, not after; check coolant and brake fluid.
  • Pests: block the exhaust and intake with steel wool or a rag, tag each plug conspicuously (a note on the steering wheel works), remove every plug before the engine is started, and leave nothing edible in the car.
  • Interior: sun shades at minimum, a desiccant pack, windows closed, and condition the leather and vinyl.
  • Run it or don’t: either start it monthly and bring it to full temperature with a drive, or leave it fully prepped and don’t start it at all; short idles are the worst of both.

Bringing it out in the fall

Check tire pressures and date codes, charge the battery, look for leaks and rodent evidence, check the brakes before the first real drive, and give the fuel system a look if it sat without stabilizer. Then it’s Run to the Sun season.

Or let it work while you’re gone

If the car is one you’re thinking of selling anyway, summer storage is money spent on a car you’re leaving. The alternative is consignment: no fees, a fair market value we agree on together, a check within 10 business days after it sells, and the car on our lot working for you instead of sitting under a cover; a broker will go over where and how it’s displayed. Our guide to selling your classic car in Lake Havasu covers how it works.

Our honest limits

This is general guidance; the manufacturer’s manual and a marque specialist are the authority for a specific car, especially on fuel systems, EV conversions and original finishes. Our service shop handles storage prep, fluids, batteries and tires.
