So to recap:

Chrome wheels = bling.
Lambo doors = ricer.

I hope you understand what I'm getting at.
The way a car door opens has no effect on the cars performance and according to you they are only aesthetic, since you say they serve no functional purpose; therefore, vertical doors would be "bling" not "ricer" according to your definition.
