I put over 500K miles on my M-B 3.0 Turbo Diesel 300D and it was just getting broken in... Hated to let it go, but the rest of the car wasn’t quiet as durable. My 300 was even SilberBlau metallic as sould appear to be shown in the picture.
Mine is black with the M-B Tex Palamino (tan) interior. Getting rough, but the engine just soldiers on.
