 I want to love Mercedes but they always go wrong. Mechanically is where this car falls. $310 for an normal service is way too much and cost for other small repairs are ridiculous like $20 for a new key battery. We only have about 40,000 miles on ours and every morning on a cold start there is a clicking noise coming from under the car. Also the steering vibrates a little on the highway and shakes when your ride over a pothole.
