Virtually all sports cars are either convertibles or come in a drop-top version. Purists would say a real sports car has to be open-air. Others would point out that a coupe offers the ultimate in chassis rigidity and tight handling, thereby making it the truest sports car form.
Besides fixed-roof coupes, like the Chevrolet Corvette, there are minimalist manual-top roadsters (
Mazda's MX-5 Miata, for example), motorized padded-roof cabriolets (Porsche's 911,
Jaguar's XK, etc.) and remarkable folding-metal-roof quasi-coupes (
Lexus' SC430, Mercedes SL and SLK).
Sports cars carry a cargoful of assets and liabilities. The pluses are obvious — mainly the fun factor of top-down driving (in the case of convertibles), exhilarating performance and head-turning looks. But they tend to cloud the minuses, which can include cramped accommodations, a stiff ride and high fuel consumption.
