OK, if you want me to make it a little more obvious for you:

1) A roll cage is a benificial addition to any car purely for safety value alone.
2) That gauge cluster is one of the stupidest things I have ever seen in my life, and it reflects poorly on your taste to want to install such a thing in your car. It serves no useful purpose, and I can imagine a lot of other good things to spend $100 on.

Is that better for you? Or maybe you would you like for me to draw you a picture? I was trying to stay polite in my post, but that was obviously not nessicary.
