I've been browsing some CART results lately. While now everybody uses Reynards or Lolas (Marches and Eagles too, some years ago), when the series started (1979 IIRC) they used their own weird-named cars like Rattlesnake, Wildcat, Lightning, Longhorn etc...
However, I also found some names connected to Formula 1 (Theodore, Spirit, even Ligier), and Sportscar Racing (Argo)
Does anybody know if there's any connection to the ones we knew in F1, or just a coincidence?
To help you out, some data I found:
Theodore:
1979: Theodore Racing entered an Eagle-Ford for Mike Mosley (no 36)
1980: idem, no 48
1983: "Master Mechanic /Caesar's" (sponsor name??

1984: "United Breweries": Theodore 83 - Ford for Jim Crawford (no 78) @ Long Beach 3/31, Meadowlands 7/1, Indy 5/27
1984: Theodore Racing: Theodore 83 - Ford for Bruno Giacomelli (no 44) @ Phoenix 4/14, Long Beach 3/31
1984: Theodore Racing: Theodore 84 - Ford for Giacomelli (no 52) @ Indy 5/27
1985: Ensign Racing: Theodore Ford for Chico Serra (no 15) @ Portland 6/16
Spirit:
1983: Spirit83-Chevy for Gary Bettenhausen @ Milwaukee 6/12
Ligier:
1984: "Dubonnet-Ligier": Ligier LC02-Ford for Kevin Cogan (no 98) @ Long Beach 3/31, later driven by Michael Chandler (no 98) @ Phoenix 4/14 for "Ligier-Curb Racing", they also used the Eagle 84SB for Cogan and the "entrant" was called "Dubonnet-Curb" then...
Argo:
1983: Argo 83-Ford for Bill Alsup (no 11) @ Indy 5/29
1984: Bill Alsup (no 27) drove following cars: Argo JM15-Ford @ Cleveland 7/8, Argo JM15B-Ford @ Michigan 7/22, Pocono 8/19 and Argo JM15C-Ford at Sanair 9/9.
In case of Theodore, the entrant could well have been the same as in F1, but what about the cars named Theodore. Note that the cars are carrying the name "83" in 1984. Would this mean they have anything to do with the car that appeared in F1 the year before?
Especially 1985 is interesting as in 1983 Theodore was racing a disguised Ensign in F1, this seems the other way around...
Should I assume Mo Nunn was involve with all post-1983 activities?
The "Spirit" seems to be used only once, on an oval. Makes it hard to believe it has anything to do with the F1-team or car.
On the other hand, the year 1983 seems correct...
The Argo is using the right initials ...
But what about Ligier???
Anybody??
