19: BMW M5 (E34)
The E34 was revolutionary in a couple ways for BMW. The car was more refined than outgoing models. With increased competition from Lexus, this was a must. A top-of-the-line straight-six gave the E34 a driving experience that still excites to this day. Very few modern luxury cars can come close to the E34 in terms of quality and drivability.
BMW has made several well-rounded sports sedans and coupes over the past few decades. But the E34 of the ’90s is close to many enthusiasts’ hearts. Its sheer power that the E34 has is at the top of the clas, not to mention the modern luxury features that make the E34 a livable sedan.
