2017 GMC SIERRA 1500 DENALI VIN 3GTP1PEJ1HG428060

This GMC Sierra 1500 Denali was built in 2017. The gearbox is automatic. The petrol engine has eight cylinders.

The record gives the mileage as 151,379 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. A car that has covered this much distance for its age has worked hard, and a mechanic should judge the wear accordingly. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. Service invoices and inspection reports each carry a mileage figure, and lined up in order they show whether the clock tells the truth.

This GMC Sierra 1500 Denali is recorded with front-end damage. A damage entry is a starting point for the inspection, telling the mechanic where to look first. With front-end damage on file, the inspection should start with the radiator support, the headlamp mountings and the front crash structure.

At the time of recording, the car ran and drove. A key was noted with 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.

The record shows a salvage title. A title of this kind usually means the car was written off as a total loss after damage. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title.

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. From the outside, a car with a repaired accident and a car without one can look identical.

A cold start, the colour of the exhaust smoke and any oil leaks tell a mechanic a good deal about how an engine has been treated. On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. Automatic transmissions, CVTs included, are expensive to repair, so the test drive should include pulling away from a standstill and a stretch at motorway speed.

A history check works by VIN because the number never changes, unlike registration plates and owners. This car’s identification number is 3GTP1PEJ1HG428060. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. A professional inspection makes sense whatever the paperwork shows, because no report measures corrosion, worn bushes or a poor repair.
