Just days after an amateur car enthusiast snapped one of the best shots of the BMW M3 Sedan at the 'Ring, an Autoblog reader snapped pics of Porsche's 4-door Panamera testing on American soil. Spotted driving on the 405 freeway in Carson, California, this green Panamera mule doesn't reveal anything new.

Herschel Brown was cruising in his BMW 330i when he came upon this mule and quickly managed to snap some detailed shots. Head on over to Autoblog to view more images.
