Ford's Fiesta and Hyundai's Accent both fall into the subcompact category, which has often included first cars for new drivers or purchased as an extra car by drivers who simply want basic transportation--usually for no more than one person.
The Fiesta and the Accent both start between $15,000 and $16,000, and you'd be hard-pressed to break $19,000 even with a heavy hand on the options list. The Hyundai is a slightly better value for money, with the more expensive base Fiesta relying on econocar classic features like wind-up windows and painted steel wheels with plastic wheelcovers.
