Whakakihia te rerenga e whai ake nei: I te roa o te kore o te Formula One paddock, i puta mai a de Cesaris i te
2005 Monaco Grand Prix, a i manakohia hoki me te awhi mahana mai i te rangatira o mua o te kapa Brabham me te rangatira o te Formula One a Bernie Ecclestone. I etahi marama i muri mai ka panuitia ka whakataetae a de Cesaris i te raupapa Grand Prix Masters hou mo nga taraiwa Formula Kotahi kua reti. I te Oketopa, i whakatauhia e ia te wa tere rawa atu i te whakamatautau Grand Prix Masters tuatahi i te tiriti o Silverstone South i Ingarangi. I matapae a Mark Hughes, kaiwhakahaere o te "Autosport" Grand Prix, ko de Cesaris tētahi o ngā kaihautū kaha rawa atu i roto i te tūranga Kaihautū Matua. I te whakataetae tuatahi i te ara Kyalami i Awherika ki te Tonga, i eke pai a de Cesaris ka eke ki te tuawha, whai muri i te pakanga kaha ki te Briton Derek Warwick.
