Six months, a year, multi-year — the protocol changes at each duration. Get the chemistry, the mechanics, and the climate right or pay for it at re-commissioning.
A classic car parked for the weekend and a classic car parked for 18 months are not the same machine and do not survive the same way. Long-term storage — defined as any period beyond 180 days — crosses the threshold where fluid chemistry, fuel stability, elastomer dry-out, battery sulfation, and tire compound migration all become first-order failure modes. Hagerty’s claim data shows that the most expensive single class of collector vehicle damage is not crash damage — it is storage-related deterioration on cars parked without proper protocol. At REVCity Auto Storage — 7185 Bermuda Rd, Las Vegas NV 89119, 725-272-1803 — the long-term storage protocol below is the one we run on every vehicle that crosses the six-month mark, whether it’s a numbers-matching 1967 Chevelle, a 911 SC, or a daily-driven E-Type going into multi-year hibernation.
The 180-day threshold is not arbitrary. It is the duration at which five independent degradation curves all cross from “recoverable” to “permanent damage” territory if the protocol is wrong.
This is the protocol we run before parking any classic for 6+ months. Each step has a measured failure mode if skipped — this is not a generic checklist.
The real cost of bad long-term storage is not the storage fee — it is the re-commissioning bill on the other end. Quantified by failure mode below, using Hagerty restoration shop data and our own re-commissioning estimates.
| Failure Mode | Outdoor / Self-Storage Risk | Typical Repair Cost | REVCity Climate Risk |
|---|---|---|---|
| Gummed carburetor / clogged injectors | High — standard after 180 days untreated | $1,200–$4,500 | Near zero |
| Rodent wiring damage | High in Nevada self-storage | $4,000–$15,000 | Zero |
| Tire flat-spotting / age cracking | High on the ground; moderate on stand | $1,600–$6,000 (set of 4) | Eliminated on 4-post lift |
| Battery replacement (sulfated) | Standard on outdoor sit | $200–$700 | Prevented by tender |
| Interior dry-rot / leather cracking | Moderate outdoor; high in heat | $3,500–$12,000 (full re-trim) | Mitigated by 40–50% RH |
| Brake system corrosion | High at 12+ months | $1,500–$4,000 | Low |
| Paint UV oxidation | Severe Las Vegas outdoor | $8,000–$25,000 (full respray) | Zero indoor |
The way a long-stored classic comes back into service determines whether the storage protocol succeeded. Rushed first start-ups account for a meaningful share of post-storage damage in Hagerty’s claim data.
