This low-mileage W212 E350 is a clean example of Mercedes' bread-and-butter sedan from the era when they still felt like real cars. The 3.5L V6 and seven-speed auto are competent if unremarkable, but 43k miles on a 2011 means you're getting into the sweet spot where deferred maintenance hasn't yet become a second mortgage. No reserve on Bring a Trailer usually means the market's ready to decide what this actually costs.
