I know that the answer to the above question is E39 BMW M5. That’s the greatest German sports sedan ever built. It lives up to the hype, and remains a case of Meet Your Heroes for me personally. Though my time in the car was brief (maybe 15 minutes), it provided everything I needed to know about the E39 M5.
There are certainly other strong candidates, of course. Our own Josh Ostrander recently acquired a B7 Audi RS4. Look for more on that car soon. The engine note from its 4.2-liter V8 remains one of the greatest audio hits in the Audi catalog.
Mercedes-Benz has plenty of winners as well. AMG-badged sedans are typically thrilling machines ready to fill the air with amazing noise and tire smoke when called upon to do so.
The answer here is still E39 M5. But I’m curious to hear your thoughts on the matter. Sound off below!
