...Coupe!? Makes no sense to me.? To my understanding I've known the "TS" to stand for touring sedan in the Cadillac line up. An example would be the STS: Seville Touring Sedan and the CTS: Catera(I believe) Touring Sedan. How can Cadillac's new coupe be called a Touring Sedan Coupe? Should'nt the car be called the CTC??? After all they did have an ETC: Eldorado Touring Coupe
