Today in the parking lot at work, I seen a older model 450SEL 4dr. It had the same body style as the 78-80 300SD, but it was longer of course. I am puzzled, because it had the small Euro bumpers and cloth interior- just like the Euro models, but it looked like a typical USA 1973-79 450SEL 4dr (other than bumpers and cloth interior). So there were also Euro 450SEL models? I was thinking that they would have a different model name than a USA model?
