1) The following interior samples were scanned from a Mercedes sales brochure "MKP 6701 0903 01-05/0789", printed in German, dated 1989, said to cover the 420/500/560SEC coupes.
2) In order to make it look halfway decent, I left the file size as 140 kB, so don't be surprised by the download time.
3) There is no way that the ink on that page, the photosensors in my scanner, and the phosphors on your monitor are all going to line up together to show you the true colors. Use this only as a general guide, not as the ultimate reference.
4) You will be even more disappointed if you try to print it!
