I'm not doubting the prowess of the CTS-V whatsoever. If all I wanted was outright rubbberlayin' speed at any cost, It would be the only option in sedans.
I've driven Audi's for so many years, and I can't seem to migrate away from the brand. Drove a C63 AMG a couple days before buying the S4 .
Great car, great sound, giant NA V8. It was fun, and raw certainly, but it lacked usefulness below 50mph other than depositing rubber on the ground and a certain refinement.
Mercedes also nickels and dimes you to death for options.
"starts at 58k" Means every new one costs at least 72K, and you don't even a get a LSD for that.
For what a bare bones nothing automatic only C63 costs, I get a fully loaded awd sedan with AWD, 7 speed Dual Clutch DSG, launch control, and the comfort of working with service personnel I've known for years.
For me it was a no brainer, a couple drives and I was sold. Not everyone will choose the same thing, thank GOD. God bless america.
