Omega spy pictures I took near Metro airport on W. I-94 about 6:00 PM, 7/11/2009.
Might be a GM Europe (Opel), with some kind of flex fuel badging rear left (not green or yellow, it's silver).
The lighting bolt logo and standard Illinois plates have me quite curious.
The handsome couple in their mid to late 20's did not look like the engineers I typicaly see.
