German Mercedes tuner Carlsson has announced a 25-unit, limited-edition C25 coupe based on the Mercedes CL and the ancient nightmares of dread Cthulu. Sure, it has a 735 hp turbocharged V12, but that isn’t why people will buy it. The real ownership pitch: Carlsson will only sell one per country, thereby “guaranteeing exclusivity” for its buyers. Which begs the question: would Carlsson have sold that many C25s on their own merits? We think not.
