It may not be the first M5 but it is the "real one." The first 4-door sedan to make a Ferrari humble and rip to consecutive series race track triumphs in Trans Am. "What do mean it only has a tiny 6 cylinder motor?" Ha. Stand on the gas and the symphonic 6 comes to life. Sure BMW has made more powerful M5s but none have this panache. The faster it goes, the smaller it feels. Truly amazing car.
