2007 CHEVROLET TRAILBLAZER LT VIN 1GNDT13S172293165

This Chevrolet Trailblazer LT was built in 2007. The fuel is petrol. There is an automatic gearbox, with four-wheel drive.

The clock stood at 168,698 miles when the data was entered. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. The number on the clock proves little by itself; earlier figures logged at services and inspections are what make it believable. A service book or a folder of workshop invoices is the simplest place to find past readings.

Primary damage in the record: left front. A damage type says what kind of damage the car had, not how serious it was or whether it has been repaired since.

The car is recorded as running and driving. A key is on file for the car. A condition note describes the car at one moment; months of standing or later work on the car can change the picture in either direction.

A salvage title is on file for this car. Titles of this type are issued to cars declared a total loss. Once issued, a branded title stays with the VIN for good, and it affects registration and insurance for every later owner.

Every car builds up a history from the day it is first registered: owners come and go, inspections are passed or failed, and repairs are paid for. Pieces of a car’s history sit with registries, dealers, workshops and insurance companies, and none of them sees the whole picture. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating. Drive to all four wheels means more to maintain: differentials and couplings have oil of their own, which some manufacturers want changed at set intervals.

Stamped into the body and printed on a plate, the VIN is the one identifier that stays with a car through every owner, registration and repair. This car’s identification number is 1GNDT13S172293165. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. A history report says nothing about the car’s present condition: the frame, corrosion, electrics and the quality of any repair are judged on a lift by a mechanic.
