We have the 189-hp 4-banger Benz, and I'm dead set on a V8 for our next car (in a few years, of course). Our car has plenty of pick-up at highway speeds, but there's just no low-end torque. That's extremely frustrating for me, especially for city driving. The engine shouldn't have to be revved to 3k rpm just to make the car move. Also, the good gas mileage only shows up on the highway; city mileage is about 19 for us. Please consider getting at least a 6-cylinder.
