This is my 3rd c class . Bad experience with the interior , the driver side seat repaired twice The Nox sensor went twice, 37,000 miles on the clock , seems like nox sensor malfunction 3 rd time Overall not happy with this car . Mercedes are known for prestige car . The older cars were very reliable, the newer c class models have common faults

Pros: It's a looker inside out for something that was purchased <$30K used with 40k miles. Surprisingly sporty without compromising comfort. Prestige that comes with the brand. Burmester system looks and sounds amazing. Cons: I took mine to an independent Mercedes specialist for service and repairs since "Service A" which is basically an oil change costs upwards of $300 for a 4 cylinder at dealerships. C300 4Matic sport pack comes with the unnecessary staggered tires. Mercedes interior creak is a real thing. interior looks very expensive, just don't touch anything. This was my daily driver and I put about 30k miles annually. PCV failed at ~60k miles. This seems to be a common issue with early W205's. At 70k miles, AC compressor failed. These 2 repairs alone cost me approx. $4k. At ~85k miles transmission started slipping, so I had to let her go. I know Mercedes are not cheap to maintain, but reliability does not allow me to enjoy the car without worry.

This model suffers from several factory defects. Problem with a vent assembly cause gasoline smell inside the vehicle. Failure of wrist pins in cylinder 1 destroy the engine.
