The Catera and the CTS have a lot more in common than the Seville and the STS. The Catera was rear wheel drive, and for some time shared the same engine and transmission with the CTS.
The Seville and the STS really have nothing to do with each other. Even the Northstar engine has been completely reworked. The STS is as all new as they come.
I loved the Seville and even owned 2 STS's and 1 SLS. Wonderful cars. However, the STS is definately not a Seville. Very, Very different character.
Bowen, since you've got all the letters figured and and what they stand for; care to enlighten us on what SRX means?
Huh? That's funny since a few years back I almost bought a '94 Cadillac STS. Look, it seems everybody, according to focus groups, likes groups of letters and/or numbers for their upscale marques.
Cadillac has had no continuity or idea what to name their cars until the past couple of years. While they promoted their FWD STS years ago and gave the SLS monikers to the softer version, they had a DeVille, Eldorado and a Catera. Just over the past few years they started playing games with the DeVille calling it the DTS, DLS and the same goes with the Eldorado.
The universe which calls itself the STS isn't all-new. Some guys are rolling around in 1st year, early 90's pushrod powered STSs. '05 has a newly designed STS. Finally what an STS should be. Too bad they took over a decade to get it right.
