2004 CADILLAC SRX VIN 1GYDE637940122578

This Cadillac SRX is a 2004 model. Under the bonnet is a 3.6-litre petrol engine. Power reaches the wheels through an automatic gearbox. Details for this car come from a single data source and may differ from its documents.

The source data puts the mileage at 298,571 miles. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. A later figure lower than an earlier one points to a replaced instrument cluster or an odometer that has been wound back. Older figures usually turn up on service invoices, inspection reports and past title paperwork.

Primary damage in the record: front end. Two cars with the same damage label can be very different: one needs a few new parts, the other major work. Given the kind of damage entered, a mechanic should look first at the radiator support, the headlamp mountings and the front crash structure.

At the time of recording, the car ran and drove. A key was present. 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. At some point in its life, the car was declared a total loss. If any work has been done on the car since, photos and invoices should show what was replaced.

Behind every used car lies a string of events: who owned it and for how long, what the inspections found and which repairs and claims were made. 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 car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

An engine that has had its oil changed on time is far less likely to cause trouble later, and workshop invoices are the proof. On a petrol engine, spark plugs, ignition coils and the cooling system are the routine items a service history should cover. 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.

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 1GYDE637940122578. Scratches, fresh paint or a replaced plate around the VIN markings are warning signs in their own right.

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 2004 Cadillac SRX, the sensible next step is a history check on VIN 1GYDE637940122578.
