2017 GMC ACADIA DENALI VIN 1GKKNPLS6HZ270202

This GMC Acadia Denali is a 2017 model. Power reaches the wheels through an automatic gearbox. Power comes from a 3.6-litre petrol engine with six cylinders, rated at 310 hp.

The source data puts the mileage at 89,776 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

When the car was recorded, it showed damage to the right rear. Whether the damage has been repaired since, and how well, is not something a damage entry can show. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

The record notes that the car ran and drove. 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.

The car carries a salvage title. Titles of this type are issued to cars declared a total loss. The structure and the quality of any work done deserve a thorough inspection on a car with a branded title, however sound the car looks.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

A vehicle identification number has 17 characters: the first three name the manufacturer, the next six describe the model and its specification, and the last eight identify the individual car. The record gives the VIN as 1GKKNPLS6HZ270202. The VIN usually appears at the base of the windscreen, on a door pillar and stamped into the body, and all of them should match the documents.

What a history report can list depends on what has been documented about the car: registrations, mileage readings, damage, branded titles and theft reports. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. A VIN check and a physical inspection answer different questions: the first says what happened to the car, the second what condition it is in now. For this 2017 GMC Acadia Denali, the sensible next step is a history check on VIN 1GKKNPLS6HZ270202.
