Get the car ready before closing the trunk
When you go away for a few weeks, the usual parking assumptions no longer apply. Building work, public demand, driveways, snow, street restrictions and other cars are likely to create a headache for the car if you are not around. Match the travel dates with a typical return period, add in any blow-outs and nobody will miss that time in the airport lounge.
Flush valuables, food, wet items and any other potential messes or known leaks. Take pictures of the outside and record the mileage before the handoff. Store travel docs separate from vehicle docs, and plan for someone to get a call if plans change. "Simple, straightforward steps are often those few that stick in the mind once the taxi is parked outside.

Double check insurance and registration directly with the providers before switching normal use.

Create calendar reminders for the final day, payment dates, registration, insurance check-up and any service deadlines. Reminders are especially important if storage is related to a larger event. Don't let the vehicle leave the plan just because it's left the driveway.
