According to the CarWow study, this vehicle scored a 98.83-percent conformity to the Golden Ratio. By the numbers, that means the bloody Smart ForTwo Cabrio is the best-looking car built in the last decade. Not a Dodge Challenger, or an Aston Martin Vantage, Corvette, Giulia, Agera, or any one of hundreds of vehicles that deserve recognition over the roofless Smart. It's not the worst, but it's so far from the best.
