This Porsche Panamera 'Stingray', customized by European tuner car firm TopCar, is one of the sickest whips we've seen this month. 

The car has a full custom interior with hand stitching on the seats and doors, complete Italian Napa leather, full carbon interior including steering wheel, door trim pieces, air vents, door handles, dash trim, center console, rear console, grab handles and shift knob.

The body features custom front bumper, carbon bumper slats, carbon front splitter, new rear bumper with air ducts, carbon rear diffuser with 3rd brake light, two piece side skirts with carbon lowers, a full carbon hood, new front fenders and quarter panels, carbon fender inserts, front and rear door skins, electronic rear door opening system, carbon hood inserts and a mean-looking 3-piece carbon rear wing.

The seller, listed as Motorcars of Georgia, wants an astronomical $299,800  for the Porsche. You could almost buy a new Ferrari with that kind of cash!
