My current bike is matte black. i chose it for 2 reasons:

1) I like the say it looks
2) It doesn't attract attention..

A few years ago I was on my Trek Madone waiting for a traffic light to change. A pickup truck was next to me and one guy leaned out and said "that bike looks expensive". He then opened the door so I took off. i wasn't going to hang around to see if he just wanted a closer look.

A matte back bike looks cheap and i'm good with that.
