In the 20 or so years they've been running it, I don't think Mercedes has ever made the list. Remember that they have a max. price cutoff of around $50k (inflation-adjusted over time), meaning that the only Mercedes realistically eligible have been the C Class/190 series and the low-end E class. C&D has shown a preference over the years for the sportier BMW 3 series (many appearances) over the baby Benz.
