I personally hate that Cadillac has gone to the series of letters rather than names. Everyone knows what a Seville, Eldorado and Deville is, but I often have to explain what an STS is although I think it is probably the best known of the letter codes simply because it has been around the longest. I guess they did it to make a clean break from the past and appear more sporty, and it is definitely workng for them, but that doesn't stop me from missing the old names.
