Metallica's James Hetfield can add another award to his Grammy trophies, this time for one of his custom cars.

The Black Pearl, a custom he designed with partner Rick Dore won Goodguys' 2014 Mother's Custom of the Year award during the Goodguys 32nd-annual All American Get-Together.

Black Pearl is completely scratch-built, not any particular make or model. Its sculpted, handmade aluminum body is inspired by the tear-drop contours and seamless body transitions of cars of the 1930s. It rests on a custom-built chassis which utilizes the outer frame rails of a 1948 Jaguar.

California's Marcel and Luc De Lay formed, shaped and built the body.

"As an artist myself, I see the passion, dedication and perfectionism it takes to be good at your craft," Hetfield said. "I am humbled by their gift of metal sculpting. The fact that they started with a 8x10 drawing and ended up with a complete car is a testament to the ability of the human mind and hands. It still blows people's minds when they ask what body we started with and we say, 'steel sheets.'"

The car was painted in a luscious deep PPG black by Darryl Hollenbeck of Vintage Color Studio, offering a contrast to the brushed brass trim. Inside the cabin is a Ron Mangus interior. Wheelsmith Fabrications made the black wheels featuring matching brushed brass caps. Under the hood is a 375-horsepower, 302-cubic inch Ford V8.

In addition to the Goodguys 2014 Mother's Custom of the Year, Black Pearl won the Sam Barris award as well as the Custom d'Elegance at the Sacramento AutoRama.
