2007 BUICK LUCERNE CXL VIN 1G4HD572X7U231448

The Buick Lucerne CXL described here left the factory in 2007. The gearbox is automatic. Under the bonnet is a 3.8-litre petrol engine.

At the time of recording, the car had covered 291,604 miles. Because the clock counts miles, any figure noted in kilometres has to be converted before the two can be compared. A single figure proves little: what makes a mileage believable is a series of readings that rise steadily over the years. Title paperwork often notes the mileage at each change of owner, which makes it a useful cross-check.

No primary damage is given in the record for this car, which is not the same as proof that it has never been damaged. Signs of an old repair – uneven panel gaps, overspray, a slight mismatch in paint – can still turn up at an inspection.

A key was present. Months of standing can leave a car with seized brakes and perished tyres.

Title status in the record: clean. A clean title is a good sign, though it says nothing about wear, maintenance or how the car was driven.

A car’s history is the sum of what has happened to it since it was new, and most of it has left a trace on paper somewhere. What a car has been through is seldom visible at first glance, and a respray can make even a badly damaged car look sound.

On a petrol engine, a rough idle, misfires or a warning light on the dashboard need looking into. The automatic gearbox should respond smoothly and without delay; jerks, slipping or hesitation on a test drive need investigating.

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 VIN of this Buick Lucerne CXL is 1G4HD572X7U231448.

Depending on what is on file, a VIN report may include past registrations, mileage readings, damage entries, branded titles and theft checks. A history report says nothing about the car’s present condition: the frame, corrosion, electrics and the quality of any repair are judged on a lift by a mechanic. The history behind VIN 1G4HD572X7U231448 is the natural starting point before any decision about this Buick Lucerne CXL.
