2004 GMC YUKON SLT VIN 1GKEC13V34R163399

This GMC Yukon SLT was built in 2004. Under the bonnet is a 4.8-litre petrol engine producing 285 hp. Power reaches the wheels through an automatic gearbox. Every figure for this car is given as it appears in the source data.

At the time of recording, the car had covered 303,609 miles. 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.

The record lists rear-end damage as the main problem on this car. A damage entry is a starting point for the inspection, telling the mechanic where to look first.

When checked, the car could be started and driven under its own power. A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

The record shows a salvage title. At some point in its life, the car was 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.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. No single office holds the whole story of a car: registries, workshops, insurance companies and lenders each keep their own part. Much of a car’s past cannot be seen: a good body repair leaves no obvious mark, and neither do years of hard driving.

An engine that has had its oil changed on time is far less likely to cause trouble later, and workshop invoices are the proof. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. The automatic gearbox needs its fluid changed at the manufacturer’s intervals, and invoices should show that it was.

A VIN never contains the letters I, O or Q, which could be mistaken for digits; its 17 characters identify the maker, the model and the individual car. The record gives the VIN as 1GKEC13V34R163399. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

Where entries exist, a VIN check can show changes of owner, past mileage readings, reported damage and whether the car is listed as stolen. A repair paid for in cash at a small workshop leaves no trace in any database, so no report can list it. The past is on file; the car’s condition today is a job for a mechanic, who can check the structure, underbody, electrics and any repairs on a lift. Before going any further with this GMC Yukon SLT, it makes sense to look up VIN 1GKEC13V34R163399.
