Get the info from the trim tag on the cowl.

The VIN tells you it is a '67 Firebird coupe built in Lordstown OH with a V8. The trim tag tells more.

It's not originally a 400 car, it's a 326 car. It has been worked on by one or more owners with little concern for doing things to original or professional repair standards. It has manual drum brakes. The wheels are not a good fit for the car. The side dump exhaust is cheesy. It looks like a mid '80s "hotrodder" build. The Firebird script on the rear quarters is just odd...and to remove them and plug the holes and match the paint will be $$.

This does not mean the car is not worthy of consideration; merely that your expectations and wallet should match what is offered. I would consider this car to be a daily fair weather driver, and would pay accordingly. The "value" as a collector car is reduced by the Camaro spoiler, aftermarket coil and cooling parts under the hood, sloppy wiring and workmanship. You'll spend time and money to make this car a good and reliable driver, but as long as the major mechanicals are in good shape, the cost should be reasonable.

I'd say $7-8K if sound. Look hard for hidden rust and repair areas.
