The FIAT 124 Spider has a base price of just below $25,000. For that money, there are very few convertibles available, among them the Mazda Miata and the Ford Mustang. While the Mustang might have the edge in straight-line speed, the 124 wins in handling. The 124 and Mazda Miata are very similar, having been developed jointly, so the choice just comes down to the FIAT's good looks.
