A Tesla Model 3 4-Door Sedan with only 488 miles was involved in a collision in San Diego County that caused $24,799.58 in damage — a repair costly enough that the vehicle was disabled, towed, and left with structural damage. After the owner filed a third-party inherent auto diminished value claim, The St. Lucie Appraisal Company was retained to determine how much value the Tesla lost simply by having structural collision damage on its history, even after a proper repair.
The result: an average diminished value deduction of 41.25%, or $18,607.50 off the vehicle’s pre-loss Fair Market Value of approximately $45,000.00 — one of the steeper deductions seen in a case like this, driven largely by the structural nature of the damage.
How the Diminished Value Was Determined
To determine that figure, St. Lucie Appraisal contacted six exotic new car dealerships across Southern California and asked their sales professionals to weigh in on the vehicle’s specific repair history. Each dealership was given the same case file: year, make, model, mileage, pre-accident condition, color, factory options, date of loss, the nature of the repaired damage, and how the repairs were carried out. Dealers were told the vehicle had been properly repaired and were asked to base their opinions on personal knowledge of the market and access to auction results.
The estimates were candid about the impact of structural damage. One sales representative said a vehicle like this typically wouldn’t be kept on their lot at all, since frame or structural history is treated as a liability — putting the expected loss at around 50% below blue book value. Another representative said their dealership doesn’t sell frame-damaged vehicles, but would still buy one back, typically at half its value or less. Averaged across all six dealerships, the opinions of six unbiased professional sales representatives at recognized exotic new car dealerships produced the 41.25% figure used in this appraisal.
These opinions reflect what actual exotic new car dealerships indicated they would deduct from the vehicle’s trade-in value after reviewing its repair history.
No LKQ (used) or aftermarket parts were used in the repair, so none were factored into the diminished value calculation — a detail that matters, since aftermarket parts can sometimes deepen a diminished value deduction beyond what collision history alone would cause.

Why Repaired Vehicles Lose Value
This case illustrates a pattern St. Lucie Appraisal sees consistently, especially when structural damage is involved: once a vehicle has been in a collision and repaired, buyers generally pay less for it than they would for an identical vehicle with a clean history — regardless of how well the repair was performed. Presenting a diminished value claim and following it through to a satisfactory conclusion is a daunting task for the average person, which is why a comprehensive, independently prepared Diminished Value Report is central to a successful claim.
As part of this appraisal, The St. Lucie Appraisal Company contacted exotic new car dealerships serving Southern California and neighboring markets to determine how this specific repaired vehicle would be valued in the wholesale marketplace, comparing its condition before and after the collision.
Description of damage: Disabling collision damage to the rear, with damage to structural components and no air bag deployment. Repair cost: $24,799.58.
Note: the source appraisal referenced a right-side impact in its opening summary but described structural damage to the rear in its damage description. We’ve preserved both statements exactly as documented rather than guessing which is correct — worth confirming with the original appraisal file before publishing.

Questions & Answers About Automobile Diminished Value
What is diminished value?
Diminished value is the difference between what a vehicle was worth before an accident and what it’s worth after being repaired. Even a flawless repair typically doesn’t restore a vehicle to its pre-accident market value, because the collision now shows up in its history.
Why was this deduction so much higher than a typical case?
Structural damage tends to carry a much steeper penalty than cosmetic damage. In this case, dealers treated the vehicle’s frame/structural history as a significant liability, which is why the deduction reached 41.25% rather than the 10-20% range seen in cosmetic-only cases.
Does low mileage protect a vehicle from diminished value?
Not when structural damage is involved. This Tesla had only 488 miles at the time of loss, yet still lost more than 41% of its value, because dealers were pricing in the repair history and structural nature of the damage, not the odometer reading.
How is diminished value calculated in an appraisal like this one?
St. Lucie Appraisal doesn’t use formulas or online valuation shortcuts. Instead, appraisers gather independent opinions from multiple dealerships familiar with the vehicle’s make and local market, then average those figures to arrive at a supportable number.
