The Mercedes 300D was a lengthened version of the earlier 300 models and designed to be an executive’s limousine competing head to head with Rolls-Royce. The prestige vehicle received a slightly detuned version of the same engine Mercedes installed in its 300 sports car models. Finished in a stately black, this is an older restoration. It would make an ideal addition to a collection of Mercedes or luxury automobiles or even as a singular possession for the vintage car buyer.
