lol i am very familiar with mercedes cars, you can spot by the long wooden panel posted above, only modern but not too modern mercedes model have it like from 2002-2009 era and only cls has this long panel, a more easy way to spot is the round air vent on the passenger side, c and e and s all had square vents, plus cls fits the description hot, classy and fast and the straight wood on the dash is a giveaway too only cls has it,
so there lots of reasons to easily say its a CLS
