2005 GMC YUKON DENALI VIN 1GKEK63U55J164528

This GMC Yukon Denali was built in 2005. There is an automatic gearbox, with four-wheel drive. Power comes from a 6.0-litre petrol engine with eight cylinders, rated at 335 hp.

The source data puts the mileage at 241,298 miles. The instruments count in miles; the same distance in kilometres is about 1.6 times the figure. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. A service book or a folder of workshop invoices is the simplest place to find past readings.

No damage type appears in the source data; that shows what was entered, not what the car has been through. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A key was there when the car was checked. Months of standing can leave a car with seized brakes and perished tyres.

The record shows a clean title. With a clean title the car can be registered and insured in the usual way.

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. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

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.

The VIN is a 17-character code assigned at the factory: it identifies the manufacturer, the model and its variant, and ends with a serial number unique to the car. The VIN of this GMC Yukon Denali is 1GKEK63U55J164528.

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. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. Look up the history of VIN 1GKEK63U55J164528 first, and let what it shows guide the inspection.
