7. Lexus GS 400

The Lexus GS 400 redefined what a luxury sedan could do in the late 1990s. Beneath its elegant, conservative exterior was a powerful 4.0-liter V8, capable of rocketing the car from zero to sixty in under six seconds—putting it in league with true sports sedans.
Its discreet styling and Lexus reputation for refinement meant the GS 400 rarely drew attention, making it a favorite for drivers who valued stealthy speed and comfort in equal measure.
