Opening the gas cap can be a challenge. I have a few Pontiac Fieros and there is a small handle on the driver's side "B" pillar which will pop the gas cap door. Quite hidden to the uinformed. After driving the Fiero for a while, then jumping into my non Fiero driver, I instinctively reach over to pop the gas door, which is not there when I stop for gas.
