How Mercury calculates ACV in South Carolina
In South Carolina, Mercury runs every total-loss valuation through CCC ONE Market Valuation. The system pulls roughly 11 "comparable" listings within a 65-mile radius of your ZIP code, then applies a base value before stacking deductions. For South Carolina claims, Mercury adjusters tend to subtract $1,000–$1,700 as a "condition adjustment" based on photos rather than an in-person inspection, and they almost always omit factory option packages (navigation, premium audio, tow package, advanced safety) that boost ACV in the South Carolina private-party market. Insurers must include the IMF (capped at $500) and title fees in the settlement, but Mercury's first offer in South Carolina frequently leaves that line item blank until you push back. The comp radius, the condition deduction, and the option-package omission are the three places where South Carolina drivers consistently recover thousands once an independent appraiser re-runs the numbers.
South Carolina case study: +$2,160 on a 2021 Tesla Model 3
A metro South Carolina client came to us after Mercury offered $14,250 on a 2021 Tesla Model 3 totaled in a rear-end collision. The CCC ONE Market Valuation report pulled comps from outside the local market and missed two factory option packages. We rebuilt the valuation using South Carolina-specific dealer asking prices, corrected the mileage adjustment, and added the omitted options. Mercury revised the offer to $16,410 — a $2,160 increase — within 25 days, without invoking the appraisal clause. Representative example; outcomes vary by VIN, condition, and policy language in South Carolina.
