The car that started it all, won the world cup rally two times for BMW and took many other victories. The old school 6 series is a car meant to be driven. With the engines said to go as far as 500,000 miles the e24 6-series is the best built Bimmers of all time. The 635csi came with a inline 6 engine with 215 hp and 304 torque. It gets great gas mileage, 18 in the city and 28 on the hwy. The M6 version was the best car probably you could get back then, with a inline 6 and 282 hp and 333 torque doing 0-60 mph in 6.1 seconds. Back then this is considered a rocket, and even right now not many vehicles could do this.This is still fast. The 6 series one of my favorites a real classic both representing the great legendary handling and power.
