My stomach dropped when the AI-generated settlement offer hit my inbox: $4,200 for my 2000 Honda Civic EK hatch. They valued it as a “26-year-old economy car with high mileage,” completely ignoring the K24 swap, the $3,000 turbo kit, and the fresh paint job I finished last month. I had $15,000 in receipts sitting in a shoebox, but the adjuster said, “We don’t cover aftermarket investments without a prior endorsement.”
Key Takeaways
- Receipts Don’t Equal Coverage: Handing an adjuster a stack of receipts after a crash rarely works. If you didn’t pay for the extra coverage before, they don’t owe you for it.
- The CPE Limit: Standard policies often cap “Custom Parts and Equipment” (CPE) at $1,000. Anything above that is out of pocket.
- Agreed Value is Mandatory: For highly modified tuner cars, “Stated Value” is a trap. You need “Agreed Value” where the total worth is locked in upfront.
- Labor is Lost: Even if they pay for the parts, standard insurers almost never pay for the 200 hours of DIY labor you put into the swap.
The “Why” (The Trap): The Actual Cash Value (ACV) Clause
The trap lies in the definition of Actual Cash Value.
Standard policies define ACV as “the cost to replace the vehicle with a comparable vehicle of like kind and quality.”
To an algorithm like CCC ONE (used by most insurers), a “comparable vehicle” is a stock Civic on Craigslist. They view your mods as depreciating factors (unreliable, wear and tear) rather than value-adding upgrades. Unless you have a “Customization Endorsement”, your turbo kit is considered a donation to the scrapyard.

The Investigation: I Called Them
I acted as a tuner with a $20,000 modified Subaru WRX to see who would actually cover the build.
1. Progressive (The CPE Route)
- The Offer: They allowed me to add a “Custom Parts and Equipment” (CPE) endorsement.
- The Limit: I could add up to $5,000 in coverage for an extra premium.
- The Catch: Anything over $5,000 required a photo inspection and a massive rate hike. They still depreciate the parts.
- Verdict: Good for light mods (wheels/exhaust), bad for full builds.
2. Hagerty (The Tuner Friendly)
- The Offer: “Modified” classification with Agreed Value.
- The Process: I submitted a build list. They agreed to insure the car for $25,000 total.
- The Catch: I had to prove it wasn’t a “daily driver” (I needed a separate daily car).
- Verdict: The only way to get 100% of your money back.
3. Geico (Standard)
- The Offer: They refused to value the mods.
- The Warning: The agent hinted that extensive engine mods might actually void the policy for “unacceptable risk.”
- Verdict: Avoid for heavy builds.
Comparison Table
| Feature | Standard Policy (No Rider) | Standard + CPE Endorsement | Specialty Tuner Policy (Hagerty/Grundy) |
| Stock Value Payout | Yes ($4k) | Yes ($4k) | No |
| Mod Payout | $0 – $1,000 (Max) | Up to Limit (e.g., $5k) | Full Agreed Value ($20k) |
| Labor Coverage | No | No | Reflected in Total Value |
| Depreciation | Yes | Yes | None |
Step-by-Step Action Plan
- Total Your Receipts: Create a spreadsheet today. If the total exceeds $2,000, you are underinsured.
- Call Your Agent: Ask specifically: “What is the limit for Custom Parts and Equipment on my policy?” If they say $1,000, you need to buy more coverage immediately.
- Switch to Agreed Value: If you have more than $10k in mods, standard insurance is a scam for you. Switch to a specialty carrier like Hagerty or Grundy.
- Appraisal Clause: If you are already in the claim dispute, invoke the “Appraisal Clause” in your contract. Hire an independent appraiser to fight their lowball ACV offer.
FAQ Section
Does insurance cover the labor I paid a shop?
If you have Agreed Value, yes (it’s part of the car’s total worth). On a standard policy with a CPE rider, they usually only pay for the parts cost, not the install labor.
Do I need to show receipts for every bolt?
For specialty insurance, usually no—just photos and a total value. For standard insurance claims, yes, you need every single receipt.
What if I bought used parts?
Save the Facebook Marketplace screenshot or Venmo transaction. It’s better than nothing, but adjusters hate it.
