I've read reviews of this car and I've read the fueleconomy government website for mileage for this car. In the reviews, the C230 gets ripped for having much worse mileage than the C350 sport. This despite having a smaller, less powerful engine.

I've also read reviews on places like the car MSN site (I'm not putting links here cause it will probably kill my post) and people note getting 30+ MPG. I have found one of these I like, but don't want to take a step back in mileage. Does anyone have a definitive answer on this? Thanks.
