1989 PONTIAC FIREBIRD FORMULA VIN 1G2FS21E1KL218738

This Pontiac Firebird Formula was built in 1989. The petrol engine has eight cylinders. There is an automatic gearbox, with rear-wheel drive. Every figure for this car is given as it appears in the source data.

The recorded mileage is 77,996 miles. The figure is in miles and needs converting before it is compared with kilometres: one mile is about 1.6 km. The mileage is modest for the car’s age, but long spells of standing bring their own wear, from seized brakes to dried-out seals. Turning back an odometer takes little skill and leaves no visible trace, which is why earlier figures matter more than the display. Figures carry most weight when they come from independent sources: workshops, inspection stations and past title paperwork.

No damage entry is on file for this car. Water marks under the carpets, rust in unusual places or a panel in a slightly different shade would point to damage nobody ever entered.

The record notes that the car ran and drove. A key was noted with the car. 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 record shows a clean title. With a clean title the car can be registered and insured in the usual way.

Registrations, changes of owner, inspection results and accident claims together make up what is called a car’s history. 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 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. A petrol engine in good order starts cleanly, idles evenly and pulls without hesitation. 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 ninth character of the VIN is a check digit calculated from the other sixteen, so a mistyped or invented number does not add up. This Pontiac Firebird Formula has the VIN 1G2FS21E1KL218738. A VIN that differs between the documents and the car, or shows signs of tampering, is reason enough to walk away.

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. 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.
