We currently own four Crossfires. Two are project cars - a black 05 SRT-6 and a white 6M Coupe. Those we just call "the black car" and the "white car", even though we have other white cars and another black car. Previously we owned an 05 AB coupe, with a literal bullet hole through the spoiler and into the trunk (missed the glass by 1/2"), that we simply call "the shot car". Yeah, real creative.
Our near and dear crossfires, however, do have names.
@QuadPrism 's black 04 coupe is named "Toothless" (think, How to Train Your Dragon). Our 04 V8 swapped SSB Coupe is called "Rapid Fire".
