I have found several hidden compartments in my S2000, but don't know if I actually have found the "secret compartment", have asked a friend with an S2000, and he didn't know what I was talking about. So where is it? And don't tell me to go looking in the air cleaner or under the rugs or something, okay?

 

It is located in your owner's manual.

 

How do I open the secret compartment?
1. Open the center glove box (the latch is by your shoulder)
2. Pull the top of the center console where the latch is up
