Are you thinking of putting your car into long-term storage? Whether you own a classic vehicle, a second car, or a ghost car used only occasionally, understanding the maintenance costs for dormant vehicles is essential. While keeping your car off the road can reduce fuel and insurance costs, it doesn’t mean your vehicle will be free from expenses. In fact, improper storage can lead to high repair bills down the line.

This blog dives deep into what it really costs to store a vehicle for months or years, and how you can manage those costs effectively.

📉 Why Store a Vehicle Instead of Driving It?

There are many reasons people choose to store vehicles:

  • Owning a classic or collectible car

  • Going abroad for work or travel

  • Reducing insurance premiums with SORN (Statutory Off Road Notification)

  • Having an extra car that’s not in regular use

  • Fleet or business vehicles awaiting future use

Regardless of the reason, dormant vehicles need maintenance to avoid future damage and costly repairs.

🔧 Hidden Maintenance Costs for Dormant Vehicles

Let’s break down the key areas where costs can creep in:

1. Battery Maintenance or Replacement

When a car sits unused, the battery will discharge. After a few months, it may go flat or degrade, requiring a replacement.

  • Estimated cost: £60–£150

  • Tip: Use a trickle charger or disconnect the battery to extend its life.

2. Flat Spots on Tyres

Tyres develop flat spots when a vehicle isn’t moved for weeks or months, leading to uneven wear and vibration.

  • Estimated cost: £300–£600 for 4 new tyres

  • Tip: Inflate tyres to the upper limit and move the car slightly every few weeks.

3. Fluid Degradation

Oil, coolant, brake fluid, and transmission fluid break down over time. Stale fluids can lead to corrosion and system failure.

  • Estimated cost for full fluid change: £150–£250

  • Tip: Replace fluids before and after long-term storage.

4. Rust and Corrosion

Moisture in garages or driveways can cause rust, particularly on brake discs and undercarriages.

  • Estimated repair cost: £100–£1,000+ depending on severity

  • Tip: Use a weatherproof car cover and consider anti-rust coating for long-term storage.

5. Pest Infestations

Dormant vehicles can attract rodents that chew through wiring and insulation.

  • Estimated cost: £200–£1,000+ in repairs

  • Tip: Block entry points and use rodent repellents inside and around the car.

6. MOT & Road Tax Compliance

If you declare your vehicle off-road with a SORN, you’ll skip MOTs and tax. But once you put it back on the road, a Ghost Car MOT ensures your vehicle is compliant without the need for a garage visit.

🧾 Storage Costs: Garage vs Outdoor Parking

Storage Type Monthly Cost (Est.) Annual Cost

Private Garage £100–£300 £1,200–£3,600
Heated Storage £250–£500+ £3,000–£6,000

While garages protect from the elements, they increase overall storage cost. The choice should depend on your vehicle’s value and storage duration.

Item Total (5 Years)
