Filling in the CTS-V blanks:
EPA estimate is 14/21. The Mercedes looks impressive here because it has AWD, is heavier, and gets 15/22 to 16/23 depending on model.
Starting price is $84k or $86k after destination and gas guzzler. Loaded up it will just tickle $100k.
It seems competitive to favorable in light of the M5 and E63 AMG. Has there been a comparo with these?
