Well, the 1966-1974 (1502 ran to '77) BMW 02 Series really put them on the map. Sports sedan, new concept. Fun to drive, functional, a blast, German quality and engineering. I bought one new in college in 1972, what a fun car to have in Colorado. When I'd drive between WI and CO, 1130 miles, the car just sang, love, love, loved it at 90 mph for hours on end. Only 4 speeds, revving like our 113s. They love it. The 2002 is prized today with the best examples selling at $100K+ I paid $4200.
