1982 GMC 5500 W5500 VIN 1GTGK24J8CF722759

This entry is for a 1982 GMC 5500 W5500. Power reaches the wheels through an automatic gearbox. Under the bonnet is a 6.2-litre diesel engine.

At the time of recording, the car had covered 172,885 miles. Miles and kilometres are easy to confuse, and a distance in miles looks lower than the same distance in kilometres. Little distance per year can mean long periods of standing, light use or a tampered clock, and only older entries tell these apart. Gaps of several years between logged figures deserve attention, as does any reading lower than the one before it. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

In the source data, the main issue is mechanical damage. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Damage rarely stays where it is first seen: an impact can reach the mountings and airbags behind a panel, and water or fire the wiring and electronics.

A key is on file for the car. Months of standing can leave a car with seized brakes and perished tyres.

The car carries a clean title. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

A car’s history answers three questions: who kept it, how it was looked after and what went wrong along the way. The paperwork is kept by different bodies – registries, workshops, insurance companies and lenders – so the history of one car is spread across many places. A clean, polished car can still hide a serious accident, a flood or years of hard use.

A diesel used mainly for short trips may need attention to its particulate filter, EGR valve or injectors. 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.

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. For this car, the VIN is 1GTGK24J8CF722759. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

A VIN report shows what has been logged: earlier registrations, odometer figures, damage entries, branded titles and theft checks, wherever such data exists. No report is complete: a repair done privately and never claimed on insurance leaves nothing to find. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. The history behind VIN 1GTGK24J8CF722759 is the natural starting point before any decision about this GMC 5500 W5500.
