Vehicle Identification and Damage Documentation
Why VIN and documentation matter
Every estimate begins with correct vehicle identification. The VIN (17 characters) encodes make, model, body style, engine, restraint system, and model year. Misreading one character changes parts catalogs, labor times, and refinish formulas. Candidates must know where VIN plates appear (dash, door jamb, firewall, under hood) and that a VIN decode or catalog lookup confirms trim and options.
Documentation practices
Good documentation is contemporaneous, objective, and complete. That means: photographs before, during, and after disassembly; a written damage description keyed to panels; measurement records; and a record of customer statements and authorization. Pre-repair photos protect both shop and customer. Note prior damage and aftermarket or modified equipment explicitly, because they affect both repair method and value.
Traps
Questions may test whether a photo alone proves damage (it does not - it documents condition). Another trap is assuming the VIN alone identifies every option; trim and packages often require a catalog lookup or door-jamb label. Watch for scenarios where a customer claims pre-existing damage after the fact - contemporaneous documentation is the answer.
Worked example / rule of thumb
Rule of thumb: document as if a stranger will read the file in two years. Example: a rear-ended sedan. Photograph the bumper, quarter panels, trunk floor, and taillight gaps; record VIN and odometer; note a pre-existing scratch on the decklid; obtain written authorization before repairs. If a dispute arises, the file answers the question without memory.
