I take it this isn't from the local NAPA?

I paid $75 for my first air filter after I bought the car. The previous owner had some quicke lube do his regular maintenance that didn't stock the filter so they just never changed it. The filter by this time had a couple of bees, some pine needles, and a lot of dirt/dust and needed to be changed asap. My mileage went up 1mpg after just the filter change.

This was before I got hooked up with my fellow Mercedes brethren on the internet. I only paid about $35 for my last one.
