The battlefield of the 1.6-liter sedans has never been this big.  Long before, people had only two choices: the Mitsubishi Lancer and the Toyota Corolla.  Pretty soon, other car manufacturers came into the picture offering their own brand of compact-sized family car.  Now, the field has no less than seven competitors: Chevrolet Cassia, Ford Lynx, Honda Civic, Mazda 323, Mitsubishi Lancer, Nissan Sentra and Toyota Corolla.  This huge array of choices makes buying a compact-sized sedan much more difficult than shopping for hotdogs at a local supermarket.
