Specialized car storage options

If you're storing a vehicle that needs extra care – whether it's seasonal or high-value – some facilities offer features designed to go beyond basic storage.

Winter car storage

Planning to store your car during the colder months? Here’s what to look for:

  • Climate-controlled units with humidity control to prevent rust, mold, and battery issues
  • Indoor storage to protect against snow, ice, and temperature swings
  • Some facilities even offer add-on services like tire pressure checks, battery maintenance, or a basic wash before pickup

Tip: Store your vehicle with a full tank of gas and a trickle charger for the best results in winter storage.

Exotic and classic car storage

High-value or collector cars deserve a little more attention. Look for:

  • Climate- and humidity-controlled indoor storage to protect finishes and interiors
  • Limited-access or private units for added security
  • Optional maintenance or detailing services to keep your car in pristine shape while it’s in storage
  • Some premium locations offer vehicle preparation and startup services upon return

Good to know: Some facilities require advance booking for specialty storage, especially during peak seasons.

How to get your vehicle ready for storage

Before storing your car, be sure to:

  • Wash and wax to protect the exterior
  • Check and top off fluids (oil, brake fluid, coolant)
  • Fill the gas tank and add fuel stabilizer
  • Inflate tires to the proper PSI
  • Disconnect the battery or use a maintainer
  • Use a breathable, fitted car cover

What documents you need to store your car

Storage facilities may have specific requirements before you can store your vehicle:

  • Proof of ownership (vehicle title or registration)
  • Valid government-issued ID
  • Proof of insurance (some facilities require it even if your car is off the road)
  • Up-to-date registration (requirements vary by state and facility)

Tip: Always check with the facility in advance, as some will not accept vehicles with expired registration or no insurance. Read your lease agreement carefully and ask about storage-specific insurance options.

How secure your car is in self storage

When choosing a car storage facility, security is crucial. Here’s what to look for:

  • 24/7 video surveillance and monitored security systems
  • Gated access with keypad or card entry
  • Well-lit premises and secure fencing
  • On-site staff or regular patrols
  • Reputation for safety in the local community

Tip: Ask the facility about recent upgrades to their security and check online reviews for peace of mind.
