Is my MGM flex fuel?

I have an 07 MGM LS, I have read everywjere that a V in VIN is a flex fuel car, which it has a V in VIN, but it doesn't have a yellow gas cap. I have read that the 07 ford cars could or could not have a yellow cap. I have done a Vin search and it says flex fuel car but I'm still not sure

My question is, is there another way to tell if its a flex fuel car besides the Vin and the fuel cap?
