It came stock on pre-2003 Proteges.. then they switched to the open style cup holders. A word of warning though, the flip-top holders were way shallow and don't really function well as actual cup holders, hence why Mazda decided to change the design.
The other thing about these is that excess sweat off cold stuff can run out of the backside of the cupholders into the console because of the flap of material that goes accross the backside of the lid. There isn't really a true cup all the way around like on the open deeper ones. I thought I wanted the covered ones too, until I got some. Scoped it out and decided to stay with my open top ones.
