The W212 E Class is one of the better cars that Benz has produced in the last couple of decades, with the sort of performance, comfort level, and build quality that the marque was famous for in the 1980s (though not quite that high).
This generation received a notable facelift for the 2014 model year, which this example benefits from. It also features one of the better motors you can get in the E Class, a smooth 3.0 liter twin-turbo V6 that churns out 329 hp and 354 ft-lbs of torque (and which is still used in the E Class to this day).
The real story here though is that you can pick up an excellent one-owner, dealer-maintained specimen like this for more than 60% off the original sticker price (which was over $70k!).
It’s offered on craigslist HERE by a private seller in the Seattle area for $26,750, which is about 10% higher than the KBB estimate. I think $25k or less would be very well bought.
