As was the case with its direct predecessor, the 450 SEL 6.9 proved an immediate success; although it was more than twice as expensive as the 350 SE, a total of 7,380 units were built during its four and a half year production period.
In May 1975 Mercedes presented the 450 SEL 6.9 – the new top model in the series and true successor to the 300 SEL 6.3.
