To promote its new West Covina, California, dealership, Penske Audi built this car over the last year as a promotional tool to drum up support for the dealership network. The V8-equipped S4 sedan wears a new custom exhaust with quad tips and has been lowered a couple inches using H&R springs over a set of 20-inch CEC C859 wheels with a custom black finish, diamond-cut lip and 245/35-series Michelin PS2s. Details include smoked taillights, color-matched mirrors, trim, grille and brake calipers. New Alcantara upholstery inserts have been placed within the cockpit and stuffed inside the trunk are 800 watts of disco madness, courtesy of Alpine and JL Audio in a custom stereo enclosure. In the coming months, we'll be teaming up with Penske Audi on a brand-new ec project car. Keep your eyes glued here.
