Story

Urban Muscle Donk takes a ’78 Caprice—already a cornerstone of big-body American style—and pushes it into modern show-car territory without losing the lowrider heartbeat. The widebody is the headline: 230mm per side of ballooned, scallop-layered fender volume that reads like muscle-car pressure under skin, with recessed lines to keep the surfaces from going flat under city lights.

Under the neon, it’s all stance and presence: a measured 1650mm track front and rear, 24-inch Forgiatos, and a hydraulic system tuned for tilt and hop while still landing clean. The small-block stays true to the era, rebuilt for reliable rumble and a deep exhaust note that carries over wet asphalt and a crowd’s noise.
