The first one was a shape shifter. Carla Connor was boss of Underworld at the time, and she drove a Black Mk2 until it got totalled by crashing into a building, but, the Black RCZ that crashed into the building was a Mk1
Continuity had a day off presumably, or, it was just cheaper to trash a Mk1 than a Mk2 & they thought nobody would notice.
I know the film you are thinking of, & can’t remember the name either.
