The real advantage of the Cessna fuel cock is that it is in a far more sensible place than the PA28 etc. If you have a passenger you can always ask them to turn it off whilst you concentrate on flying the aircraft. (Remembering to tell them to tighten the safety belt when done).You can't do this with the daft positioning in the PA aircraft. (I also hate the single door idea.) I cannot fly a PA28 without a FI or safety pilot who can fly the aircraft whilst I grovel about as I cannot reach the fuel cock, but the C152 is fine (not tried a 172/182).

Great aircraft the Cessnas - two doors, accessible fuel cock, windows which you can leave open in flight, great heater in winter, cool air in summer, etc

and the wings are in the right place.
