Okay, so I have a general question. I just bought a new Crossfire last week, quite a jump from the Mustang I had. I haven't had to put gas in it yet. I noticed when you open the fuel door it says PREMIUM FUEL ONLY in big bold letters. How true is this? I'm sure premium helps the car run better, however regular gas is much cheaper. How much damage (if any) will I cause using the cheaper, and old reliable REGULAR gas??? Also, does anyone know if there is a cargo net that can be purchased to put in the trunk? I see some kind of hooks back there, but not sure what they are for.

Thanks!
