How to store a classic car for the long term

Short answer

Keep it dry, covered and secure. Clean the car, fill the tank, connect a battery maintainer, and use a breathable cover. Then drive it, or at least run it up to temperature, regularly. Humidity and long periods without use do more damage than kilometres.

Before storing

Wash and dry, including underneath
Fresh oil and a full tank
Tyres at the right pressure, or on stands for long periods
Battery maintainer

While stored

Dry, ventilated space; consider a dehumidifier in humid areas
Breathable cover, never plastic
Check for rodents
Keep insurance current; check your policy's storage rules

Keep restoration evidence

Keep dated photos, invoices and specialist reports with the car. For Japanese performance cars, instrument-cluster work can affect odometer and condition records; a specialist such as Tachofi can document the cluster work it performs.
