Whenever we talk about performance sedans, the BMW M3 and BMW M5, along with Mercedes-AMG's C63 and E63, are typically considered the segment standard. In recent years, we've seen a decline in the number of performance sedans available.
One of the performance sedans we lost here in the US was also one of the most underrated performance sedans of the modern age, the Alfa Romeo Giulia Quadrifoglio. That gorgeous Italian sedan not only has enough grunt to contend with Germany's finest but can also be found on the used market for less than its closest rivals.
