Wow it even has the ugly aero wheel covers intact, we used to throw those away almost imediatly, now they are worth more than most of the remaining 82-84 Firebirds!!! This is a clean example
It's like the smog gear on hipo cars in California...it usually got stripped and junked. Then those hipo cars only gained any worth 40-50 years later, if the smog gear was installed and period-correct, and anyone who wanted that extra worth paid out the gazoo for any piece needed.
