A salvage brand is a permanent mark on a vehicle's title record. Understanding how it is applied explains why branded cars are cheap and why the discount rarely disappears.
Total loss is an economic decision
An insurer declares a total loss when the estimated repair cost, plus related expenses, reaches a threshold relative to the vehicle's value before the damage.
That threshold is set by state law or insurer practice, so an identical car with identical damage can be totaled in one state and repaired in another.
Because the comparison is against value rather than against safety, an older car with modest damage is totaled far more readily than a newer one.
Branding is a title action
Once the insurer takes ownership through the claim settlement, the title is surrendered to the state and reissued with a salvage designation.
The brand attaches to the vehicle identification number, which means it persists through resale, and states share this information through a federal title database.
That database is why moving a car across state lines to obtain a clean title, historically known as title washing, is much harder than it once was.
Rebuilt is a separate designation
A salvage vehicle usually cannot be registered for road use until it is repaired and passes a state inspection, after which the title is reissued as rebuilt.
The inspection generally verifies that parts used were not stolen and that the vehicle meets basic safety requirements, rather than certifying repair quality overall.
A rebuilt title therefore means the car was returned to legal road use, which is a narrower statement than most buyers assume when they see it.
Insurance and lending treat it differently
Liability coverage is normally available for a rebuilt vehicle, while comprehensive and collision coverage can be harder to obtain or valued differently at claim time.
Lenders are frequently unwilling to finance branded vehicles, because the collateral is difficult to value and to resell if the loan defaults.
Those two constraints, more than the damage history itself, are what keep the resale discount in place through every subsequent transaction.
Disclosure rules govern the sale
Sellers are generally required to disclose a brand, and history reports draw on state records, auction data and insurance reporting to surface it.
Records can lag or be incomplete, particularly where damage was never claimed, so a pre-purchase inspection remains the check that examines the car rather than the paperwork.
Because thresholds, inspection requirements and disclosure rules are set state by state and revised over time, the treatment of a branded car varies by where it is registered.
