Cadillac STS
Sold alongside the Seville, the STS was another offering that GM sold to consumers. But the STS had a different focus than the Seville as this was the performance-oriented Cadillac model. The STS was a lot faster and there were subtle things done to the appearance. The STS was advertised as a lot heavier than the Seville was in an attempt to attract more buyers (via Motor Trend).
The interior of the STS was also slightly different, with performance-oriented seating and a floor-mounted shifter. The suspension was also different from the Seville, which was designed to compensate for the added performance. When it comes to hidden performance gems from the 1990s, the STS was one of them.
