The Chrysler 300 is already one of the coolest things to come out of Detroit in recent memory.

Much, much cooler: this one-off Chrysler 300S customized by John Varvatos.

Varvatos and Chrysler collaborated on the car to benefit his pet charity Stuart House.

Valued at $75,000, it features custom Varvatos hallmarks on the chassis and waffle weave accents on the interior, along with swathes of sumptuous black leather.

Other bespoke add-ons include Mopar 20-inch wheels in satin carbon finish and various tailored touches.
