I remember a few from 2003:
- F3000 teams Arden and the short-lived Brand Motorsport were linked with entries, the latter would have brought back Nicolas Minassian, the former could have had something to do with the fact that one of their drivers that year was Townsend Bell who had recently driven for Patrick Racing.
- The stillborn BC Motorsports team that intended to run Giorgio Pantano.
- Kurt Busch tested for Team Rahal but Bobby Rahal had already signed Michel Jourdain Jr.
- The late Justin Wilson was linked to Newman-Haas Racing before signing for Minardi in F1.
- André Lotterer was linked with a full-time switch to Champ Car after his one-off debut with Dale Coyne Racing in 2002.
