Beautiful cars! I've got the coupe version of that sedan. I know in my neck of the woods, any purple E36 is a very rare sight, I don't think I've seen one yet. May I ask what's the story with yours (i.e where has the car lived, how long have you had it, mods)? What I find common between the E36 M3 and F87 is that they don't take themselves too seriously, which I love.
While this is an aftermarket paint job, my friend's LS swapped Miata is painted in Daytona Violet. It was interesting to see how much more red was in the color, whereas Techno had more of a blueish hue.
