As a young engineering student I flew in the ex Hughie Greene Cessna 310 - due to the effects of trying to evade the soviet fighters the airframe was somewhat distorted and it did not want to fly straight. The small baggage door on the right side was also prone to coming open in flight.I think he was wise to get rid of it. I met him some years later when he had a push pull Cessna - he did not appear to be a very happy man.
