[2] Wilson joined the team after a crowdfunding effort by his father, and former F1 driver Jonathan Palmer after Justin had missed out on a drive with Jordan Grand Prix in 2002 due to his height.

[19] He suffered from exhaustion and temporary paralysis in the neck during the 2003 Malaysian Grand Prix due to his HANS device coming loose and restricting arm movement inside the PS03 cockpit.

[27][28] Minardi quickly signed Nicolas Kiesa, who did not score any points but finished all five Grand Prix he competed in driving the PS03.

Minardi started the year with a primarily black car, featuring heavy sponsorship from owner Paul Stoddart's European Aviation brand.

[30] At this time, Dutch business Trust upped their sponsorship and the car gained a black & white split livery.

Ron Dennis and Frank Williams were particularly against supporting Minardi, and this was heavily criticised by then FIA president Max Mosley.

[35] By October, Italian newspaper La Gazzetta dello Sport claimed Minardi had been sold for 2004, this was later refuted by owner Stoddart.
