Although the MINI line-up, comprised of the Cooper and Cooper S, underwent a major redo last year, it's hard to see the changes until you get up close. The tiny cars have been an undeniable success, selling in numbers far exceeding parent company BMW's expectations. Hallmarks of the two-door four-seat hatchback's design include sporty handling, distinctive styling and more interior space than its small exterior dimensions might imply. The popularity of MINI has helped to expand America's acceptance of small cars and in many ways defined the premium small car market. Competitors to the MINI are varied and include the Volkswagen Beetle, Chrysler PT Cruiser, Mazda MX-5 and Audi A3.
