Lots of talk about liking or not liking the SLC43. And talk about the bellowing SLK55. Since I have had both, I thought I would comment. The 55 certainly sounds better with the V8 howl and burble at idle. And according to MB, the 55 is a tenth faster in the 0-60 (US) time. But I can't tell it. The 43 has almost instant torque and that seems like the biggest difference when driving it. I think the max torque comes on in the 2000's range vs. 4000 range in the 55. And the front end weight difference is noticible when cornering. The 43 does not plow like the 55 did. I have seen road tests lamenting the disappearance of the 55 from Mercedes's catalogue and the dismay that the replacement of the 43 is inferior. But what they are forgetting is the huge price premium the last 55's brought. The 2016 55 I considered had a list price of $84k in U.S. Dollars. The 43 I just purchased listed for $67k. This is certainly a reason that the 55 sales were so poor. For that kind of money, there are a lot of choices (even MB models) that are very appealing. So apples to apples, I think the 43 is a good deal. The 2016 SLK350 - a naturally aspirated six cylinder with 306 HP and 273 TQ sold for $67. My SLC43 at the same money is a lot more car.
