YACT: What could a rust-orange stain on the garage floor mean?

[RollWave]

I've rearranged the cars in my garage many times, so I'm not quite sure who the culprit is, but I saw this orange stain that sort of worries me. Anyone know what that could be caused by?

EDIT: Oh, and let me add that this is toward the rear of the car somewhere around the rear axle.

or rusting on his undercarriage?

Automatic Transmission Fluid is red. Maybe it's that?

new AT fluid looks like cherry cough syrup. Used is usually dark reddish gray or black.

Nocturnal emissions. Happens when cars get older.

coolant/anti-freeze is my guess, too

Well 1 car is a Lexus LX470 thats 2 years old, I know its not that one. The other two are a 92 LS400 and a 99 Viper RT10. Hrm...maybe the check engine light this time isnt a false alarm?

differential fluid would be the likely source at the rear, but I'm thinking it could just be rust.

Since the Viper is never out in the winter I highly doubt its rusting. The 92 lexus has been regularly serviced since we bought it and is in MINT condition. It only has 50K miles on it after 14 years of use. The LX is just too damned new to be rusting, I just refuse to believe it would rust that quickly.
