Considered to be BMW's pride and joy, the E9 replaced the 2000C and 2000CS in 1968. The three-liter BMW coupes were very popular during the seventies. More of a symbol than a profit-making range, the coupes were a statement that BMW had returned and would be successful. Each and every coupe was built by Karmann in north-west Germany. The 3.0CS was considered to be too heavy, cumbrous and had a distressing tendency for rusting away.
