My parents have gone through Mercedes and Porsche. I like both of those, but I don't think I would ever really want one. I think you'd actually have to pay me to drive a C55 or any C-class in general.
The S4 just doesn't have anything special about it. I like how when you see a 4.6/4.8, you know it's one of those because of the exterior features. Although the RS4 is a beast, I test drove one of those a month ago or so.
At this point I'm just searching around for opinions and thoughts, still not positive about really trying to sell my car. But it would be fun to get into a car, that's the only thing that's keeping me thinking about selling...
