The high prices, as mentioned by
@MichiB and
@Satanicom, are largely driven by the Manufaktur program. If you are configuring a decent speced W223 S450d non-LWB (AMG line, nappa leather, Burmester sound, dynamic seats heated and cooled, panoramic roof et cetera, you'll end up at approximately € 140.000-€ 145.000 (after discount).
But if you're taking Manufaktur paint € 11.781, Manufaktur interior package € 11.000. Manufaktur leather € 13.000 you're adding € 36.000. If you order the rear seat package plus and premium plus package with digital extra's (mobile office) you're adding another € 27.000 in no time. And I'm not even mentioning the additional obligatory extra's you have to take if you choose the M. interior and leather package.
