So are we saying the Cadillac Seville has rolled up onto the same plateau as a car like the LexusLS 400? Not yet.We can say that the price of all that heady horsepower is a pretty hefty thirst for fuel. Part of this is due to a little-old-lady-from-Pasadena syndrome that tends to seize STS
drivers - you can't keep your foot off the accelerator. But part is due to the car's sheer mass. GM just can't seem to keep weight out of its luxury cars, and though the STS is about 100 lb. less than the Oldsmobile Aurora, it's no wraith.
However, the biggest gap that Cadillac has to close between itself and Lexus has to do with quality. The Lexus LS 400 has established quality standards Cadillac and everyone else in the industry are still chasing.
But judging by the fit-and-finish of our test car, we think it's fair to say that Cadillac is steadily gaining ground.
