Since I have the W108 and W109 together I thought I'd make a video with some of the differences. I also cover U.S. vs. Euro and year-to-year differences in these cars. Both models were available with a variety of engines, some only in one or the other, i.e the 300SEL 6.3 and the 280SEL. No 108's were made with 6.3's and no 109's were made with the M130 six.
