2016 MERCEDES-BENZ CLA 250 VIN WDDSJ4EB3GN349437

This Mercedes-Benz CLA 250 is a 2016 model, finished in black. Power reaches the wheels through an automatic gearbox. Power comes from a 2.0-litre petrol engine with four cylinders, rated at 208 hp. The specification is taken from the source data and has not been checked against other documents.

The clock stood at 96,629 miles when the data was entered. A clock converted from miles to kilometres should be documented, since the swap can hide the true mileage. Services and inspections note the distance covered, so a car with an ordinary past builds up a trail of figures that climb year after year.

Primary damage in the record: front end. Whether the damage has been repaired since, and how well, is not something a damage entry can show. A lift and a diagnostic check show what photos cannot: bent brackets behind a panel, chafed wiring or deployed airbags.

A car that does not run has to be moved on a trailer, and its real condition is known only after a thorough assessment. An engine that will not start could have a simple electrical fault or internal damage, and only diagnostic work can tell which. 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.

Title status in the record: salvage. A title of this kind usually means the car was written off as a total loss after damage. A branded title follows the car through every change of owner, so it remains part of its history.

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. A car’s paperwork is scattered: the registry knows about owners, the workshop about repairs and the insurance company about claims. A car’s past rarely shows on the paintwork: a well-repaired accident or water damage that was dried out is easy to miss.

When a car does not run, a compression test and the condition of the oil tell a mechanic whether the engine can be brought back to life. Many modern petrol engines are turbocharged and direct-injected; where they are, the turbocharger and injectors belong on a specialist’s checklist. On a car that does not run, the automatic gearbox cannot be judged on the road; the colour and smell of its fluid and a diagnostic scan give the first clues.

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 WDDSJ4EB3GN349437. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

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. However complete the paperwork, only an inspection shows the condition of the body, suspension, brakes and electrics today. With this 2016 Mercedes-Benz CLA 250, the first step is a look at the history behind VIN WDDSJ4EB3GN349437.
