Thank you. I like her too. The Catera is basically an Omega Elite. Mine, being a Catera Sport, is also equipped with the MV6 suspension pieces. All Cats are 3.0 V6/4 speed autos. The Sport comes standard with Elite 17 inch wheels and the rear wing. I prefer your spoiler but it would cover the center mounted brake light in the boot lid. Inside, the faux wood is replaced by satin silver trim.
The lights you mentioned are called cornering lights. They come on with the turnsignals. They don't blink, and are supposed to illuminate the turn. Their output is meager so I don't see how they can warn you of anything. Besides, my eyes are already focused through the turn. I think they're a useless piece of fluff.
One of these days I'll have to upload new pictures. My car now has a black mesh grill with a Cadillac crest & wreath. I also bought a different set of alloy wheels, similar to the Steinmetz, to use with my snow tires. If my son ever returns my camera I'll be sure to post pictures.
