Opel's Insignia OPC is one of those "available elsewhere" cars that's got us licking our chops.

What's not likely to make any trans-Atlantic journeys is a wagon version of Opel's performance-enhanced sedan. Spy-shooters have nailed an Insignia OPC Sports Tourer running about uncamoflaged, and the wagon's got its sights trained on Audi's S4 Avant.
