well, first Jlinn, the Civic SI is not a "special" edition vehicle. It is a regular production "high" performance model. It is a trim line of the Civic. The Corolla special edition will only have a limited run of examples, thus "special" edition. Second, the Corolla XRS was the "high" performance trim that was dropped. One reason it was dropped is because people had a hard time saying Corolla and High performance in the same sentence and sales were not strong enough to merit an XRS model in the new style. Will Toyota bring back the XRS? who knows.
