>>What's the strange little black circle on the right rear quarter panel??
I would guess it's the hole left behind from a police cruiser antenna. It's a beauty, ain't it. It a sign of battle scars and should be shown proudly.
BTW, Nice car nick. one of the sweetest 9c1's i've seen that has maintained it's caprice styling (to a point) and still looks sporty. (no offense 9c1 guys)
